Re: "We could not activate Battlefield 3" PC

I don't know what I did (at least 95% sure that this is how it fixed for me) but mine is working

C:\ProgramData\Origin and delete everything in there

and

C:\ProgramData\Electronic Arts and deleted everything in there

the restart your computer

When re-opening origin it will say updating on anygames you have downloaded wait for it to complete and cross your fingers

Not sure if it will work for you or if this fixed it but this is how mine started working.

Also I ran cc cleaner before hand but that didn't fix it after the first restart.
