I joined the STCC server which was running the same combo as on the screenshot but alt-tabbed to windows (i know i shouldn't) and left it to load. When I maximized LFS it displayed an error which I can't remember but anyway it didn't let me join. I then closed LFS and started it again with pitspotter, tried to join the STCC server in a normal way but it was full so I went to SP mode to play with the XFG souds a bit. I wasn't able to go to the garage and when I clicked "add AI driver" it told me there is a race in progress. Going back to the start-up menu didn't solve the problem and changing the track didn't solve it either. Only restarting LFS did.
