MusicIP not recognizing stored analysis when buliding library

Hi all,

I have about 18k tracks and all of them have the fingerprint results of MusicIP stored in the tags (i. e. option "archive analysis"). As I am moving from a Windows installation to Raspberry, I have to rebuild the default.mp3lib (as this only works with v1.8.1 and my existing default.mp3lib was done on Windows with v1.96b).

I thought rebuilding the library with v1.8.1 should be fast as I have all the analysis results stored in the tracks. However, none of the tracks in the MusicIP GUI show up as green after adding my music folder and it wants to do a full analysis on all 18k tracks. Obviously, I would like to avoid that.

Any ideas re. what I am doing wrong?

Thanks in advance
