How that happened I don't know (I suspect a bad shut down), but its easy to fix (just reset it), but Reason blocks the interface from opening. I needed to use Reaper to reset the desk.
Alls well that ends well I guess, but I might ticket this if if continues to happen.
Thanks for posting the solution to your issue! That rarely happens! Kudo's!
