MC 4.05 doesn´t start with analog Mojo

MC 4.05

I used to work with the combination MC 4 and my Mojo a lot many years ago.

Now I need to digitize Hi8 tapes and need to use the combination MC 4.05 and analog Mojo again.

But now, when starting MC, I get the error: "problem with hardware, power cycle your hardware." then MC quits.

I power cycle Mojo and start again, but same error. I restarted the computer, but same error.

Without Mojo I can run MC.
