Here's one for ya. A half hour ago I had a KHPro file open that I had last worked on back in July (in the version of KHPro current at that time). This time around I modified the colors and lyrics, swapped in a new version of the music file, and retimed the lyrics to the new music. I then exported to a bin file and saved the KHPro file. I then decided to reopen the KHPro file to create a vocal demo track. When I tried reopening the file, KHPro told me that it was created in an old version of KHPro and couldn't be migrated to the new format!
