Ok, fixed..
Apparently i have to use a wire, cant play w wifi

already tried without firewall, didn't work

I checked my host file, i did not have those lines in it.
Just for good measure i tried to add them just to see what happened, and while those lines were in, i could not connect
to the main server at all.
So removed them again, but still get disconnected.

I must have tried playing multiplayer about 40 times minimum now, but every single time, after a while, anywhere between 20 secs and 2 mins into the race, I get this message: "The match was interupted: Connection to [ip-adress] failed or disconnected from server (10022) Returning to menus."...
