Hello, Vicpas! What are you talking about - very strange. The English version is no different from the Russian, except for the translation. A Russian version of the mod tested friends on the forum, and worked as a mod at once.
The work of mod should not in any way affect its name (literal or digital). File extension does not change. Accordingly, the Q3 Engine recognizes the format .pk3 (zip) and the fact that within the archive.
Thanks for the tip. But I think the problem is not in the mod. Maybe, in some versions of the game is binding .dll to the order of names or set some Punk Buster. Maybe I'm wrong.
Or even easier. Look, can you just turn it off. There is such a function. If the Main folder at the moment there is a file SWM _SP.zzz, then the mod is turned off.
