So, suddenly when I opened RSRBR Alone I got no Stage selection window or Car or Stage info window. I have tried to reinstall, but it didnt work. And now I cant drive any stages alone   Need help soon as possible

This is an order or a request?  

I just need some help. I want to get back racing soon!

You ask for help,  I know, but there is a polite way to ask and not "...soon as possible"
Because you have forgotten: "Hello, please, thank you..."

You are new to the forum but have you ever played the game he has already worked on your computer or is this your first installation?

"RSRBR Alone problem"
Alone only? Public and championship?

Launch RSCenter and give a screenshot.

I have played RSRBR alone for atleast 30hrs already. And only Alone is not working, everything else works fine. And yes I know I could have asked more polite, but I was mad cause it had just stopped working for no reason...  So here is a screenshot of RSCenter. http://imageshack.com/a/img924/301/GzIb91.png

Close all windows RSCenter.
Download Depannage RSRBR
Start and click on the button below ""Repositionner les fenêtres de RSCenter"" then choose the interface to reset.

If unresolved problem, you can play solo from the P or C interface is the same thing.
1) Select the  parameters: car,stage ...
1) Click directly on GO

Thank you! Thank you, so much! It solved my problem! Now I will get to race again!  

Good game
