Sorry to hear about that problem, but we certainly never saw that in testing, and there were a lot of eyes on it (so to speak). It may well be a bug, but it sounds like it could be specific to something in your system configuration. I think starting with a complete uninstall, making sure to delete all existing TG2 files (in the install directory, /program files), would be a good idea. Especially if you simply installed over your existing version rather than uninistalling and then installing the new one.
