Mezzmo 3.0 installed and hangs at 100% CPU (i7 3770!)

[BeFi]

I installed Mezzmo 3.0 today and ran the recommended library maintenance. It stopped at Processing active playlists 7361 files remaining. 100% CPU load on a Core i7 3770k. 30% of this load generated by Mezzmo, 70% (/-) caused by the Behavioral Analyser of my GDATA Virus Protection. Mezzmo hung - no progress visible. I am running Win8 64k.

I then killed Mezzmo - the behavioral analysis stopped as well. Result: 0% CPU load.

Restarted Mezzmo and Library maintenance. Result: 100% CPU load, 30% Mezzmo, 70% Behavioural Analyser of GDATA. Mezzmo working at first through the library then hanging again at 7361 active playlist items remaining.

Result: I wasn't able to complete the library maintenance. I am back to Mezzmo 2.7.1.17 with the 2.7.1. library.

Compare this to Mezzmo 2.7.1.17 on the same platform and with 100% the same items in its library: CPU Load with Mezzmo library maintenance running: 5-7%, Behavioral Analysis 0,4%!

Disappointment: No functional improvement visible in version 3.0. What justifies to label this a new version?

Best regards
