help. GM MDI not showing up in Tech2 anymore

dont know what happened but tech2gm software cant detect GM MDI interface anymore.
at software start I select always Gm MDI, boshch, and than on second screen there always used to be GM MDI but now it doesnt show up.
I tried different usb cable. restarting etc. still doesnt show up.
what can I try or how can I test what wrong?

Did you recently update the firmware for your MDI? If so downgrade it again and don't update it any more.
