Hi, I have been using rFactor 2 and rFactor for a long time now and this is the first time I post. I recently changed some things on my computer and went back to my old settings and now rf2 wont launch and hoping someone can help me. Things I have changed and changed back from last time rf2 was working for me. I changed to a computer monitor from a TV monitor and went back. I went from Thrustmaster softwear to Immersion software and went back. That is the only thing that has changed and I was using Build 660 already before I made the changes. The game did work when I made the changes before I went back. Except with Immersion software game slow down really bad. I have deleted the Immersion software now. I have tried reinstalling rf2 numerous time now. When I use launcher nothing happens now. Error message when I try using Troubleshoot compatibility. It try's to apply applies Windows xp service pack 2 then... "This application failed to start because it could not find or load the Qt platform plugin "windows". Reinstallation the application MAY fix this problem." I have Windows 7 installed on my PC. I have tried running everything as administrator. Can anyone help me out?
