Hello guys! It has been a very long day, started with me wanting to play some f1 2013 but was unable to launch it. a window pops up "preparing to launch f1 2013" and then it closes down and the windows pops up again, repeat infinity. So i figured i'd play some f1 2014 instead but i got the exaclty the same problem. And it seems to be just the Codemasters F1 games that wont launch. Here is the things i have tried: Reinstalling both games, changing to fullscreen and window mode both games without success. Turned off steam in game, origin in game and all sorts of programs. Cleared out appcache and finally deleted all settings in documents/my games. Reinstalled Nvidia drivers. Tried running the games with 1 monitor and 3 but no luck there either. Removed one graphics card and tried running with out, turning on/off sli. Removed my wheel and tried with xbox controller instead. And here is where it gets really fun. Just for the heck of it i reinstalled my computer today, Windows 8.1 pro fully updated and all graphics drivers installed and ALL games works as they should... except f1 2013 and 2014. I still have exactly the same problem and i cant think of anything else to try. Have googled quite a bit and tried the fixes i found but so far it has not been working well. I played f1 2013 just a few days earlier without any problems at all. Is there anyone having similar issues or have found a solution for this? Help would be greatly appreciated, have spent many hours on this today. Help me obi1! PS, have the following hardware i5 2500k 970 sli 8 gb ram, Win 8.1 pro.
