Unable to locate Avid hardware...
 

I have not used Pro Tools Se on my computer since 28. march 2012. It worked fine then. But now when I try to launch Pro Tools SE I get this message after a few seconds:

Unable to locate Avid hardware. Make sure your hardware is connected and turned on. Click "OK" when the hardware is ready.

Help!! Please!!!

The Fast Track C600 IS connected, on and works just fine using the Fast Track C600 control panel...
