Hermod+ freeze after updating 1,0,2

I have updated my working good Hermod+ and after a successful update…

My hermod started to act strangely
it got hangup very often, I need to turn off the power to get it back on track again…

Please help?

my connection is
Octatrack master Clock to Intellijen 72 case, the Midi output to Hermod+

before it works very fine

I really appreciate any help you can provide.
