Hi Tony of the Wiltshire variety,
Because you are able to save & load from GTL on the hard drive, files do occasionally get corrupted.
If the track is keep crashing the game I would think you have 2 options.
Option 1.
a. delete the track from
GTL/GameData/Locations as it may have become corrupted.
b. Reinstall this track by going to your
Archive Altbierbude/AddonTracks folder and opening the zipped file and cut & paste it to were you deleted the file from.
Option 2.
a. Uninstall GTL using the uninstall feature on the GTL disk (do not delete files by hand).
b. Reinstall the GTL game with the GTL diask and do not forget to all reinstall the 1.1 patch.
Doing it this way will not overwrite your personal data such as Profiles and set ups etc, but if you are worried make a back up of your 'UserData' file.
This always works for me so I hope it works for you.
Cherrs,
Gee-Dee
