I'm pleased that you got it working.
Generally, a new version / reinstall can be just installed over an existing version. I understand that BiaB writes very little to the windows registry, perhaps some information on Fonts, but not much more.
At any rate, you resolved your issue so that is the desired outcome.

Also, please mark your original post as resolved as has been suggested. This can assist others in the future
