I could play online perfectly fine for a while when suddenly...a message popped up which said that the game is blocked with a firewall and it needs authorization.

Well...i checked the Windows 10 firewall and the exe and also the ut2004-win64.exe.
I just cannot see why this message appears which also prevents me from playing online or on lan because when i click on OK i'am taken back to the main menu.

HELP! Please!


Edit: Solved by starting the game with administrator privileges...who would have known that.
