I just purchased Acid 11 and tried to open some music I had created with acid 10, but I get error messages. This happens regardless the file extension.
There is no program called Acid 11. There is a program called Acid Music Studio 11 which is a cut down version of some version of Acid. I imagine if the saved file includes stuff that is only available in Acid 10 you'll get errors. Yjere's a good chance that Acid 10 files would always be incompatible with Acid Music Studio.
Thanks sorry for using incorrect terminology. It turns out I just discovered I can open 10 files in 11 I just have to use the file browser at bottom of the screen instead of the file menu open command.
