Several people seem to have this problem. Perhaps one of this suggestions might help:
- make a new drivers profile
- patch to version 1.1.0
- make a re-installation in the updater
Did you use the DVD-Key for logging in instead of the Online-Key? If yes, start "regedit" and alter this entry HKEY_LOCAL_MACHINE -> SOFTWARE -> Wow6432NODE -> 10TacleStudios -> GTL -> KEYS --- tipe in the Online-Key. After that make a new drivers profile.
If this still doesn't hele: Some members write that a r-einstallation of Windows and GTL had helped.
