UR44 lost input/output signal

Hi everyone,

I’m trying to figure out a problem that has appeared with my UR44 in recent days that I can’t find any answers for.

Recently upgraded my mac to Catalina 10.15.4 and for a few days my UR44 was working fine through Logic, however yesterday I seem to have lost all input/output signal. Please help!

I’ve downloaded new drivers ect but still no luck.
