Need Assistance with an Error

[A.K Commando]

So I can't join the TTT server any more as I get dropped because apparently Gmod cannot decompress some data pak....anyone got any ideas. If required I will get a copy of the error to put up here...

Whenever this occurs on most any mod, I find it the easiest, although probably not the most fun, way to fix an issue is to delete the mod and its corresponding folder,  then reinstall, fresh...

Alright so just uninstalled Gmod and reinstalled, still can't get into the TTT server for some reason. The error that pops is as follows:

Izma.Uncompress Failed in Datapack!

Any help that'd allow me to get into the server would be fantastic.

Hmm.  Odd.   PM the TTT head admin.

I was kinda hoping he was going to check out this thread to help but you tell me who I gotta Pm and I shall.
