Dynamic Mix Plugin does not work under 7.9

Hello Forum,

since I switched from version 7.8 to 7.9 the Dynamic Mix Plugin does not work anymore. Anything else is working fine. The problem is, that I can not interact with that Plugin anymore. Not via HTML nor with Squeeze Comander.

Will there ever be a fixed version 1.4 of Dynamic Mix Plugin or do I have do downgrade my LMS to version 7.8.1? (Hoppfuly not).
The Dynamic Playlist Plugin is installed an working.

Or ist there any workaround to get it useable again?

Thank you for any help.

Greetings
