I am pleased as punch that i have my ports open and that i can host, last problem is unofficial tracks,if i put up a monza no prob, i put up spa and there is a conflict with others joining.If another player hosts say Spa i can join if i host spa people cant, i have tried reinstalling the track but no joy.I have add on skins in mine from the presto updater ,could it be this that's interfering if so is there a remedy,i always steer people towards the presto updater as it resolved other issues for me and i love a one click fix, do i get them all to use presto or am i barking up the wrong tree? When players join is says 3 Spa.gdb mismatch, i have reinstalled that file but no change,i think this is cause of most players being booted.
