Ah, the reason others were getting a mis-match with my car is i already had that small patch installed from my TPG races. I had thought that after the race i'll let Dave know about the patch so he can apply it to all, but was under the impression it was just a 'time-scaling' fix, so hadnt considered it to be a major flaw that might affect the racing as we dont race using time-scaling.
I thought it would just get rid of the 'mis-match' messages.
No Mark,
When I say time scaling I mean that if you don't use that patch your race length will only be like 2 or 3 laps, instead of say 25 or 30. See I think the root of the problem is that the skin pack wa designed for 25 minute races, but we wanted to do races of different length and that was causing a problem with the existing gdb file.
