Hi Steve,
Yup! It works fine. I'm using it right now in fact without any issues.
Keep this in mind...
Like Windows Vista and Win 7, you need to run the program as administrator. It's also recommended that you install outside of the C:\Program Files (x86) directory as well.
The issue you are seeing is related to TS12. Have you patched? This supposedly fixed some of this, although it's still an issue. I'm in the process of relocated bridge abutments which I am finding scattered all over the place.
