Hey fellow dirt hogs, Recently down loaded RBR and installed the 2010 MOD from Ralleysim. The mod installed easily and all I believe. However when I try to join a public rally through the RS CENTER I get a message that says: PHYSICS FILES ABSENT YOUR INSTALLATION OF RBR2010 IS NOT VALID. OK what do I check for at this point to verify my installation is configured properly. I see lots of RBR10 files in the RBR folder. Program files/eidos/RBR is my path. When I go to the RS Center here is what I do. Select PUBLIC SESSIONS Coordinate the clock on my PC w/ the RS Center clock Select a rally and hit the giant GO button then the physics files window pops up and no joy from there. Any help is appreciated!
