I just upgraded my Studio One version from 3.5 to 4.0. The upgrade went in without a problem. I opened songs I was still in process of working on, and they opened and played with the 4 upgrade fine. I added a track to two songs, and saved them. When I tried to re open either of them, I get an error message saying the song is from an old format and is not compatible? By appearance, it looks like any song I did before the studio one 4 upgrade is now not able to be added to and then saved, and still be useable. How do I finish projects that I was still working on? Shouldn't Studio One 4 be compatible with it's earlier counterpart, especially the most recent, 3.5?
Thank you graciously
