Hi byork,
Thanks for your wuick reply.
Last Weekend I fixed for the moment that I am fefuelling with the not wanted MSFS Fuel Tool and the FSA Client works in a "read only" Mode.
The isloting of your two Folders didn't help for, now.
The next days I will deinstall all Community Projects, Mod and so on and reinstall then step by step again to investigate in which kind of combination or which Tool produces the failure and makes me possible to describe excactly then how to reproduce the failure.
I will share my result with you then here in that post.
Thanks for the moment.
