I followed installations instructions and run database to get Navigraph AIRAC 1813 and it seemed ok.
When trying to run EFB2 server it check for updates & license (everytime!)
Then it just crashes with message.
I have P3Dv4.3 (with FSUIPC5.4) and bought your EFB v2. Followed its installation instructions (it created a folder with 2 subfolders Server & Client).
It doesn't work even though Database is brought to up-to-date Navigraph
