Happy new year everyone!

First of all thanks for the release of update 9! Nice addition.
I used the winter to build a new pc and I just reinstalled RSRBR last week. It installed without any problems, run without any problems and was able to do a little test using my G27.
Now, my steeering wheel doesn't work with RSRBR anymore. Runs fine with any other game but not in RBR. Problems started (I think) after I restore my backup.
I think I tried everything to make it work again but still doesn't work. I don't know what it could be. Can it be some software issue on my new pc or is it something wrong in the settings inside RBR?

Hope there is anyone how can help me, thanks in advance.

Hello

as-tu changé de système d'exploitation?? tu es sur W10??

si oui, regarde ici: viewtopic.php?p=613084&f=6#p613084

You could at least give some details, we're not magicians.  
When you go to the doctor, you do not wait for him to ask you where you feel bad, you tell him: I come because I have pain here.  
RBR sees the steering wheel, or does not see it ...
iIs the return of force that does not work ?
And the first thing is to give information about your PC configuration; which version of Windows, did you put the right drivers for this system, etc ...    

Alright docter but I don't know where I have pain. These are my internal organs:

My steering wheel does not react in game. Works with any other game without any trouble. But last week I tried one stage and it worked fine. Now after restoring my rbr backup it doesn't work anymore. My first thoughts are something went wrong while restoring my backup. Only problem is I am not a docter how could know the answer or even able to operate myself. I hope you know the answer to my problem. If you need more information, please let me know. Thanks!

Thank you for the detail of your configuration, I did not ask as much !  

First, try this:
Delete the 2 Mulligatawny.* files that are in the ../Saved Games  folder .
Open RBR (Rscenter must be closed).
Create a new profile "MULLIGATAWNY" in which you redetect your steering wheel,
and re-set your commands.
Save, and test.  

Is your backup of RBR / RSRBR done with the tool "backupRSRBR.exe" or is it a simple copy of the game folder ?  

Thank you Oural! It works!!!

I tried the same solution myself before asking the forum. But I did it while Rscenter was opened      
Force feedback olso works fine. I did my backup with use of the "backupRSRBR.exe" tool.

Thank you!

Happy for you .  
Have fun with the new update 09.
