Hi Oskar,
As you suggest above i uninstall and install again the Server and Client with Admin Rights and exactly as the Manuals say without any change of paths.
After completing the Installation set up the Database according User Guide "4 Database", hier the Support-File that is exactly the same as i send to Tuesday
I make one Test Flug Zurich/München and on the Runway in Zurich EFB reloading and at the Ende near München again reloading see build the problem stays hier.
I have Win10 and many others Programs: EZCA2, Active SKy16, PFPX, FSiPanel, Navigraph,SteveFX and many Airplanes and Scenerys, but all work with EFB1 from Februar 2016
till now without any problem.
So i hopp that you can help me, if not, i must stay bei EFB1. In my opinion V.2 is better, but with this problem I will wait a time, perhaps you find a solution for.
Tanks for your help
Alvaro
