... much trace of TB from my computer as possible - even doing some manual registry cleaning (do NOT attempt if you do not know what you are doing!), but no change.
This leads me to believe one of two things:
1. The latest 32-bit version has the same bugs.
2. If you upgrade to the 64-bit version ruins TB, even if you downgrade to the 32-bit version.
Just posting this to let people know, so they can make an informed decision before doing anything.
