Hey there, I was playing DST with my GF, side to side with LAN, but suddenly (actually after I scanned her PC with YetAnotherCleaner program) we couldn't see each other through LAN anymore. We tried to disable our AV programs, even our Firewalls but the result remained the same. We are playing in online now but the connection is not good as it was with LAN. How can we resolve this issue and return to play on LAN? Many thanks.
