In most cases using a No-CD or Fixed EXE will solve this problem!
When this happens use the original EXE to play online, else you could find yourself banned from the game!
Some No-CD/Fixed EXE files work fine in Single Player mode but are detected to be modified when trying to play online.Always make a backup of the files that are overwritten by the File Archive, as the original files are usually required to update the game to a newer version or to play Online!.Game or Patch Questions?
