You description is a bit like saying:
"My computer suddenly stopped working - what is wrong?"
You need to provide much more detailed descriptions of your problem before any of us have a chance to help you.
Try to describe exactly how your equipment is connected, and what exactly happens.
(how is everything connected? can you turn on the psu? how is your pc and audio interface connected to the d8b? etc...)
