i'm lvl 53 and almost every single server i connected all my custom classes are locked, i asked people in the server and there classes are fine. somthing wrong with my game?

try rename it maybe?

If you played on HighXP server, your stats are probably fu**ed...

Are maybe u trying to use something really lame and retarded in your classes(fmg akimbos or dead man hand/last stand)?if so i think the server owner may block the classes that have those selected

Depends on how are they locked ? In the CaC menu or in-game ? If they are locked in-game, then you have something the server owner blocked.

they locked in game (in a server),and i checked almost every server and same result.

Hm, try setting every class to default one.
