I just bought a key online for F1 2011. I assumed it was a Steam key that I just entered into Steam. The website looked legitimate and I still believe it is but it turns out what they were selling were CD keys. Obviously I don't have the CD. Is there any way I can use this without buying the game again or have I messed up?
Two options, download a backup of the disk and rather than crack (which is illegal) it use the legitimate key. That or find someone who has the disk and borrow it and enter your serial. The latter is the better option because despite owning the game the law is unclear as the weather you can download a backup.
Check what the site recommends because if they're not steam keys they will almost certainly have face this problem before.
BTW the game is good. I'm planning on setting up my old computer in my living room just so I can play it with a wheel.
