ProMods

The free download and the paid download goves you the same files.
The only difference, in the free download everything is split up into 7 parts as a multi-part archive, and you can only download 2 files @300kb/s where on the paid download you download 1 full archive for 1€ at the highest speed your ISP can give to the servers where the paid file is hosted.
It's just there for the users to decide wheter they want to download 7 files at slow speed, or want everything immedatly for a small donation.

You have all the files you need to play

Guys, it's still not answering why the 7 files don't show. Where is the "one" file that we pay bandwidth for that you would otherwise download for free in "seven" parts. That's why I took screenshots of the old and new files.

promods-assets-v242.scs - promods-assets-v243.scs
promods-map-v242.scs - promods-map-v243.scs
promods-media-v242.scs - promods-media-v243.scs
promods-model1-v242.scs - promods-model1-v243.scs
promods-model2-v242.scs - promods-model2-v243.scs
promods-model3-v243.scs - promods-model3-v243.scs

Those two sets of files are from version 2.42 and the new version 2.43, the difference is the file name; 242 versus 243. I downloaded 2.42 through the 'free' option at the time but decided yesterday to 'pay' for the new version/quicker download of 2.43. When I downloaded 2.42 I had those 7 extra files, what is the file name of the 1 file that would've downloaded in the 'paid' yesterday?

I understand the difference between free and paid of course, yes, we're paying for the bandwidth but surely the files should be the same. The assets, map, media, model1, model2, model3 are in both options but the free option has promods-v243.7z.001 through promods-v243.7z.007, those files whether 1 or 7 files are not there.

You still didn't understand the difference between the paid and free download. In your Screenshots you're not missing anything, all files are there.
promods-v243.7z.001 through promods-v243.7z.007 is not supposed to be in your Mod Folder, those are just the split archives from the free download. If you paid for the download you get one Archive where you can extract the files, when you use the free download, you download the 7 files promods-v243.7z.001-promods-v243.7z.007, extract the first one to get the all ProMods files.

promods-v243.7z is the single file paid download for:
promods-assets-v243.scs
promods-map-v243.scs
promods-media-v243.scs
promods-model1-v243.scs
promods-model2-v243.scs
promods-model3-v243.scs

While promods-v243.7z.001 to promods-v243.7z.007 are the files for the speed limited free download, that contains:
promods-assets-v243.scs
promods-map-v243.scs
promods-media-v243.scs
promods-model1-v243.scs
promods-model2-v243.scs
promods-model3-v243.scs

promods-v243.7z.001 to promods-v243.7z.007 are the multipart version of promods-v243.7z.
The multi part files correspondens to as if you would get a "Milk half pint" each time you go to the shop. And you need 4 pints.
The single download correspondens to as if you would go and get "Milk 4 pint" once.

promods-v243.7z.001 to promods-v243.7z.007 are the half pint containers.
promods-v243.7z is the 4pint container.

Do NOT forget to download promods-def-st-v243.scs or promods-def-v243.scs separately.

I have downloaded the payed version and have the 6 files and downloaded the def-st file aswell i put there files in the mod folder and cant load the mods in game because there is a red light with unusable behind it

Then you're either missing on of the reuqired dlc. You need Going east, Scandinavia, France, Italy and Baltic sea dlc, or you've the wring game Version. You need 1.36 for ProMods 2.43.

I bought the paid version and put def and the promods into "mod" folder but when I try to join the ProMods server it says "One or more map DLC dependencies could not be found. They are requiered for playing on the ProMods map. What Am I missing? PS. I have Scandinavia and Going East

As the information there says, your missing one or more of the required Map DLCs. You need:
Going east, Scandinavia, France, Italy, Baltic seas.

Yeah then this just kinda sucks cause i just spend 1 euro on nothing casue I cant afford Italy and France and on ur site i couldnt even see that this is MUST HAVE and all that stuff. You should pointed out more.
