Help please
 

cl.snap.serverTime < cl.oldFrameServerTime


i get this message when i am playing for more than a few 20 minute rounds, it takes me back to the main menu, ive totally reinstalled, and it still continues to happen, if someone could help or let me know how i can fix it, it would be very much appreciated, im not sure if its one of the mods i use or not, like blood, scope, crosshairs, different skins?!?!?!?!? im not really sure.

Much thanks in advance

Sincerely,
Cyan

First remove all mod, custom maps etc. then try paying. Is it better now?
