Everytime I quit serato, it loses all the bpm from tracks that have been analysed.
I have tried to rebuild the id3 tags to v2.3 in itunes but this didn't help.
My library is stored on an external harddrive, Mac OS Extended (Case-sensitive, Journaled, Encrypted).
At the moment I haven't found a solution. I'm not yet willing to erase my external drive in the hope that a different file system might work.

Thanks in advance for the Help
