Well first answer is RB hasn't been around for 6 years. That doesn't matter though as it probably feels like 6 years if you're having troubles.
Send me a PM & I'll give you my email address to send the file to. I'll check it out.
Just for the record I have over 200 songs that were done in BIAB and then just opened in RB for completion. I use these 200 + songs to play live and they never fail me. I set up about 15 songs per set X 4 sets. Hit play and away we go. Best Band I've ever had. The point is something is wrong with:
1. Your computer setup
2. your songs
3. Or the way you're trying to do things.
I will confess that RB/BIAB are not perfect. They do not have a large high paid staff to trouble shoot every little issue nor to make it 100% humanly friendly. I would not want that to happen.
