EuroScopeFsdServer need PublicVatsimLicence.lic file which could be downloaded from:
https://drive.google.com/drive/folders/1rsBunTadLEvUpljJk-Jd0jL7Mqe18GFw
Unfortunately, the webpage http://www.euroscope.hu is down and I would [Mod - Happy Thoughts]ume
that PublicVatsimLicence.lic checks the validity with the webpage.
Thus, very sadly EuroScopeFsdServer.exe could only be started 4 times thereafter,
the program is locked.
