I saw some people report this problem with many previous Engine Versions.
When update like 4.1.0 goes live and database approach is changed, that blocks me and other from updating our mixers.
Temporary solution is to revert the software to 4.0, but that forces me to format my USB (not to mention SSD) every time i want to upload new music into it, while my mixer is on 4.1.0…
Dear Engine team please consider different approach to this kind of drive reading problem and for example mark the files as unavailable not block the access to the software.
Because of database performance optimizations added with this release, Collection Databases used in Engine DJ 4.1.0 are only compatible with version 4.0.1 or later.
