Dernier message de la page précédente :
think i allready had it installed, but i installed the latest 1 anyways and still no luck.

the same message again

starting to think it might just be easier to format re-install at this point.

But if u have anymore suggestions please let me know.

Can you look if you have this file at the root of the game : 7z.exe
I think that is lock by an other program and it can't uncompress the physics.

the file 7z.exe is both there and unlocked to be sure i replaced it with a copy of the file from a friends install along with the physics file just to make sure but....still the same problem.

Make this :
- Open RSCenter, select a pack of cars, select a car, select a country etc.. BUT SELECT NORMAL MOD
- Clic on the button "Go" (you'll get an error)
- Don't close RSCenter
- Open the folder of the game
- Open the folder named RSRBR
Tell me if in this folder you have a file named Z.7z

After that you can close RSCenter.

RS center auto closes as soon as i click ok, but while the message is up and before running it the file does not exist

Then RSCenter can't extract it from the file XYZ.7z... why ????

Try this :
- Go to the folder where you have installed 7-zip
- copy the file 7z.exe in the folder of the game (otherwrite the file with the new one that you have installed before)

Make a test to know if you can launch the game with RSCenter.

ok so ive copied 7z.exe over the RSRBR installed 7z and still the same problem

Finaly, the Problem is fixed now.

Simply just formated and re-intalled windows...now all is well and game works fine.

I wonder what was causing it?

A ghost on computer
Seriously, perhaps just a little file missing or not, an update (windows or other pilots...).... it can be everything  

So, we're happy that your game is ok now.

Good game
