Thanks for your answer kep1a.
Unfortunately I tried to load the original rcc and reload my rcc file but there is no change...
I don't think it is a touch pad problem because all is responding well, I can navigate and push the buttons (they have changing colours when they are push), I would say that it could be the IR emitter which doesn't works....maybe?
I email my reseller and here is what he answers me:
"be sure the IR is not disabled in the settings as this is done sometimes with the base station, PLease clarify the problem so I can be of more assistance."
What do you think about it ? I don't understand what he is talking about when he says "disabled IR Settings", I can't see it in the software.

Thanks for your help
