Thank you for sharing the error message. Usually this is an indicator of an older version of the BeatBuddy Manager (BBM). Check that you are using the latest version of the BBM. You can find the BBM Legacy versions here: BeatBuddy Manager Software 1.64 (Win/Mac) LEGACY
Something else I noticed that might affect your BBM and that’s the use of special characters in the names of songs. The BBM does not like them and some users report that it corrupted their projects. You might want to rename file names containing @ / ( ) periods and commas.
If you haven’t tried it yet, you might have better luck with the BBMO that has replaced the BBM.
