UR22 blinks when MIC on and does not work when off

Hi guys,

This issue happened randomly last night. I plugged my mic into the input and turned it on (+48) then suddenly my speakers started acting up so then I turned off the UR22. I turned it back on and now the red lights (+48 and peaks) started coming on even when I didn’t have the mic line on. The USB white lite was on but no sound would come out of my speakers although my mac book pro picks it up. When I turn on the +48 in the back, the white USB light keeps flashing and the speakers make an awful boom sound repeatedly.
I have no idea what is going on, any input would greatly help, Thank you!
Also would I be able to get a replacement from Steinberg?
