i had this problem recently... and it happened during one of the most important gigs of my studio existance... we were in the middle of tracking drums.. and the light just shhut of... and thge screen locked up in a blue screen error... i was like wtf... so i rebooted my comp... i tried to turn on the digi 002.. and it wouldnt... it just clicked... the optical out on the back .. its light was going on and off... clikc , click, click, .. it was like the unit was strugglin to find a sample rate. so..... we sat there for 5 minutes, turned it back on... and it worked... it happened 4 times that day, and i was about to throw up of fear of it happenening a 5th time that day. SOOOO.. that was a month ago.. i have had 2 gigs since then, and its been fine.. so i dont know man, just figured i would share this story with you to let you know it pisses me off also.
