I will remove everything and start all over again
That would be the best idea!
After you did a reinstall open the extractor, add a new game, do not use auto setup and enter a name for the entry, then enter the exe, choose dirt2 (codemaster) plugin and press add game. Close the extractor and select on the right side the new game. There will be two questions which you have to answer with yes. After this insure in the popup window that the graphic driver and force feedback driver is disabled.
Start the converter and then the game. Use the quick start manuals to make a profile.
