Hi, I hope you guys can help me. Recently I get weird CTDs. The sim crashes and goes back to the desktop. The rf2 sound keeps playing. Also rfactor is shown in the taskbar but I cant click on it to activate it. When i hit alt-ctrl-del to show the taskmanager, rfactor is not shown. So i cant activate it and I can't close. The only way to get it to run again is to restart the computer. I have these CTDs only with rfactor. Ac and sce run fine. I have an i7 processor and a R920 videocard. I run win 7 64 bit. I use rfactor through steam. Has anyone else been in this situation? What could be the cause? What should i do? Thanks!
