Hello Jeff,

I'm not sure if this is the problem you were having, but there was a bug fixed in December with individual track renders being out of sync when there were tempo changes. Either way, you can make a backup of your 2020 version by copying the bb\bbw*.exe files. You could then reinstall 2021 and install the latest patch. If you have the same problem let us know. You can always revert back to the previous version by copying back the 2020 bbw* files.
