Hi! First post here (after looking for and trying solutions since friday.. spent 4 hours... today another 5 hours. I'm done and frustrated) From the beginning.. ...since 2009 I used to race a lot with Rf1.. a lot. With Rf2 not that much due to lack of time.. even though from times to times.. Yesterday I decided for the first time to buy some content to be more motivated to race againg. Bought the offer for the 4 tracks and a GT3 cars pack. It happens that Le Mans, Nordschleiff and Sebring won't start. I get a message of "failed to alocate memory due to 32bits .. etc". Ok. I get to look and my system is really running the 32bits version (even though I never had any problem with the old Nordscheleiff or even Targa Florio) Unchecked the "force 32 bits" and the game doesn't load. Black Screen. Unninstalled everything... reinstall. The same. Tried everything.. admin rights.. non admin.. run missing components from steam.. reinstall.. win updates.. deactivate antivirues.. etc. My System: Win7 64bits AMD Radeon HD7850 2GB 16Gb RAM Thanks!
