Hello.I bought crysis 2 limited edition.I have put the redeem code here.I open the multiplayer mode and it shows me level 5 with all the bonus unlocks and features.But when i am playing a game im back to level 1 without any item unlocked.Also generally when i quit game after unlocking something and open the game again it resets everything ive done.What happens?

how can i solve this?

Its a well known problem that everyone is having at the moment. The game only chooses to save your progress (this includes unlocks, classes, absolutely everything) when you LEAVE a ranked server. If you want to do anything, even change your custom classes around, connect to a ranked server first and do it there then leave.

That is the only work around at the moment. Crytek are aware of this problem and hopefully they will fix it soon because it is extremely annoying.
