UR 824 Direct monitoring died

Hello folks
My trusty UR 824 just gave up. The direct monitoring function just failed. Never happened in any other device!. Im lucky I still have and old RME HDSP in my system so I was able to re-patch my studio and use the UR in stand alone mode as a converter. Tried reinstalling drivers, no go.
Is it possible that a system crash would damage the direct monitoring function? (it works fine on the RME)
Thank you in advance.
