Seem to have same problem - Failed rF DVD launch
ISI rF Note Dec. 2010
I can't understand all of the Italian entries here. But, I seem to have similar symptoms with my rFactor DVD now also. When attempting to launch rF, the DVD spins up for 5-10 seconds with simultaneous small splash screen, and then quits with no error messages. Interesting that my rF installs all stopped launching completely on the same day that bitto69 started this thread. I have successfully used the DVD since purchasing rF 3 years ago. It is my favorite sim, of many. So far I have tried the following to fix it with no change:
1. Cleaned DVD with lens cleaner and micro cloth. It was practically like new still (stays in the drive most often

2. Cleaned registry with CCleaner
3. Swapped optical drive used and confirmed other games that check DVD, startup OK (minor problems with 1 of 6 other games launching).
4. Disabled Avira Antivirus protection. However, some parts of it were also updated on 12.10.10 - Hmmm...
5. Tried adjusting time clock forward or backward. Based on other threads this seemed to help others with similar circumstances, although they may have had PC system changes involved.
Can you throw me a bone for further troubleshooting? I am about out of typical checks.
Looking forward to rF2. But, would like to keep using my current rF mods. and tweaks!
