Battlefield won't save

Make sure you don't have BF3 beta on your hard drive. If xbox or playstation, i hear that can be a problem.

ive never had it but if i did how would i know?

Look through all the games that are installed on your system. But if you never installed the beta on your system then it wouldn't be there.

Also try deleting your "player data" in your saved folder. Let it reset itself, although make sure you copy the file first for safe keeping. It will delete all your campain data but that isn't really a problem.

(For Xbox)

Go to your Xbox Dashboard
Go to System Settings
Select Memory
Select your hard drive
Go to Games
Select Battlefield 3
Select the "Profile Save Data"
Delete It

Just searching this up cause I have the same problem. Thanks ausninjaknifer, your suggestion worked.
