Analog four not working

Well I’m stuck!! After my analog four stopped working straight after I updated it, I’m now unable to work. I’ve been waiting for the support from elektron to contact me but that was over a week ago. My machine stops on the elektron for logo on screen.
Has this happened to anyone else?

I don’t have an A4 but on the rest of the (older) machines, there is a special boot-up diagnostic mode. Might want to have a look in the manual and possibly run some of those diagnostics while you are waiting for support.
