Do you have (or had) any other MIDI devices / apps open recently?  Windows always had a way of hogging the MIDI ports.  There is/was a method for freeing them up at the system level (which I don’t recall offhand).

I recently had a similar kind of issue with Novation Circuit Rhythm.  The unit was no longer plugged in, but I believe it was Novation Components still running in the background.

Once I squashed that, H90 Control opened up just fine.
