Last night the unfortunate happened, finally the OS on my gaming PC gave up the Ghost! OCed the crap out of the board and CPU, after several crashes finally the OS was corrupted to a state the PC didn't even recognize there was a OS on the drive. It was 3+ yrs and it was time to re-install the OS. Bad part was True Image cannot re-image with previous backups. Anyway re-installing every damn software I use. Question: I need to re-install BF3. What is the process to re-use the same key? If I install Origin and login with my credentials will it allow me to re-install BF3? Or do I need to buy another key? Please advise.
