This is starting to piss me off. Every time I want to search for an exp race it cancels the search instantly and starts a new XP race lobby, which apparently no one can join. Then if I cancel the lobby it makes I am disconnected from the server until I do a career or quick race. Is this happening for anyone else? I'd really like to be able to race online.

Yea I couldn't get into an xp lobby either

There have been lots of situations with networking in mutliplayer games being messed up at launch, hopefully they'll patch it.

Yeah, I'm getting the same thing too. It's strange, because I was playing the game when it first came out in continental Europe (so this time last week) and I was getting 8-10 player matches off the bat. Then when it came out in England it just all stopped working as well. You're lucky to get a 4 player match right now.
 
Have to assume it'll be patched before the week's out. I guess it's an opportunity to get some stuff created and beat the career mode though!

It was pretty rough at first but for the past couple days I have had no issues getting in to an XP race.
