ProMod Multiplayer Join Problem

[Alumani]

Hey, I have a problem with ProMod.
Have downloaded everything and inserted it in the folder, the ProMod has the version 2.52 the mods are recognized and in the Singel Player everything works. If I want to play in multiplayer it shows me and that in the mod folder files missing.
Is it because I do not yet have the 2.55 version?
If so, where can I download the?

Thank you

I bought it but downloaded the old version I have to buy it again to have the new one?

Yes, you pay for the download bandwith not for the mod itself.
