Hi, yesterday i have updated my Windows 10 from 1909 to 2004 (May 2020 update).
After update i have delete Windows.old, because normal program works fine.
Today i'm try to login EuroAion server and the launcher report this error. I'm try to reboot, move EuroAion folder to another drive, download a new copy of client via torrent, but everything don't work
I can't downgrade the system because i've delete the old version folder of Windows 10.

Anyone have an idea? If possible i don't wan't a reinstall fresh system because have installed many programs and it's a problem for me to reinstall all.

Ty for all idea's.
