Alright, I probably should start by saying that I'm completely new to rFactor, and while I generally have no problems working with computers, I'm not a big fan of programming, but will be able to understand basic instructions with no problems.

Here is where I currently stand; I purchased rFactor about a week ago, and have installed it on my computer, that runs Vista if that means anything, with no problems. It is activated, and I have been learning the menus and racing with most of the cars. The main reason I bought it was for the stock car racing. I have GT Legends and GTR 2, and will eventually get into the road racing aspects of rFactor as well, but I've had a desire for a Stock Car game for years and upon joining Race2Play it has been my number one goal.
So I have downloaded the TPSCC Version 1.1 addon, as well as R2P Stock Car Challenge rFm. Also for good measure I downloaded the first 5 tracks listed by Tim in his article on the subject, and several of the carsets.
Here is where I must admit my ignorance. I then ran the exe. file of each of the two programs, installing ver. 1.1 and the rFm file into the rFactor folder on my computer. The program ran, it seemed fine, and at the start menu of the game itself there is the option for TPSCC v. 1.1 listed. I also installed each of the tracks, as well as the patch for them. Yesterday I then attempted to sign up for the Nevada race, the Las Vegas 150 last night. I knew I wouldn't be up to speed, but I wanted to see how that game would work. Each time I tried to connect using the correct password, an error message would pop up telling me that my version is not compatable. I believe that I'm running the most up to date version of rFactor, as it was just purchased a few days prior.
My question ends up coming to this. Is there a listing of how to install all of the files needed, or even a list of what files need to be in what areas of the game folders? Is there anything else I need to do that I overlooked? Looking at the schedule I have until the beginning of January to get everything settle, but is there a way to check the internet connections before starting.
I appreciate any help that anyone can offer, once this is all settled I can start working on my driving ability.
