My point was, RB creates some default stuff. This may not match your 2016 settings.

An example; maybe the old program was installed under an account with administrative rights and the new install user has more limited access to some things .. maybe even as simple as access to a folder on your drive.

For example, if your temp audio directory is located in User/johnDoe/temp/ and you are now running RB as user/jeffPro it may cause a problem.
JeffPro may not have access to johnDoe's folders.

This would be rare, but your issue seems pretty rare also. Lots of users have upgraded without issue, so I was reaching for straws.

May be best to just let support take a look.

Make your sound your own!
