Frankfurt would be severely light polluted. I was thinking of Mesa Redonda or Texas Star Party, if you've kept those locations. They're further south & have very dark skies, so they might make a good test to be sure that you have things set up properly. Also since they're built in, they're easy for other users to run as a comparison. That way there's no need to share your Location.

Depending on how much customization you've done, I'd wait on the Uninstall/Reinstall until Greg suggests it.   It could be something simple.

Just a suggestion,
