I am having a similar problem. I worked for hours on a song, saving intermittently on an iPad. Finally finished and tried to save, and I got a message saying my song was corrupt, and GB quit. I tried force closing and then reopen ing, but since I quit on the corrupt song, I would get the error message and GB would close again. I reset GB In settings and was at least able to open GB, but that song was still corrupt.
I opened the last copy of the song and started working again, saving intermittently again. Wouldn't you know it, just as I was about to save and go back to my songs, this file was once again corrupted. This has now happened a total of four times.
is this a GB issue that needs an update?
Is there something I am doing wrong?
Is there any way to fix the files, or open them on my iMac...I would really hate to lose so much work.
FYI. the error message reads "Warning, damaged song (Ginst)"
