Thanks, it works now.
Didn't even know there is a newer DWC version.
The hole Github system is too strange for me.
Different websites for stable version releases, beta versions, DWC and firmware. Also downloads and release notes are separated.
And there isn't an info (in DWC) if there is an update available. If you aren't very forum active, you will never know if there are newer versions.
That should be a lot easier!
