Well it's my 1st time playing crysis multiplayer yesterday and I redeem my limited edition code for multiplayer which gets me to level 5. So I unlock a dsg , a suit modules and some dogtags. During a game my comp crashes and when I log-in back all my unlocked weapons , suit modules , dogtags were gone Is there any solution to fix this?
