Hi all, I'm new to the Race 07 scene, but have run dedicated servers for other games in the past. I frequent another forum, where we're trying to get a group of people more interested in online racing, and figured we'd start where racing did. One of my friends has put together a set of old cars (mid 50's - mid 60's) and a set of British racing tracks, which work absolutely fine in single player. The problems start when we try and run multi player setups. I've got a couple of hosted servers, so figured it would be a case of just installing steam, adding the maps, running the dedicated server. After about an hour of messing about and getting fed up of having to constantly log in/out, I bought a second copy of Race 07 on steam to use as a dedicated, dedicated server account. I add all the cars/tracks to the respective locations in the gamedata folder and they're available on the car filter/event selection. When clients join however, the 'fun' starts. I find that I can use the old cars on the tracks shipped with Race 07 without issue, and that I can use the cars shipped with Race 07 on the additional tracks. However, if I try and use the old cars on the additional tracks, the clients get booted with Server <playername> "" mismatch And they are then greeted with the 'booted as possible cheat' message. What I don't understand is why I can use the cars and the additional tracks separately but not together. Am I making any really obvious rooky mistakes? Thanks in advance.
