Have you tried to re-image the MC Pro?
Here's a download link to Avid's "PRO EUCON SUPPORT" site:
http://avid.force.com/pkb/articles/e...-MC-and-MC-Pro
There is this download link to "MC Rescue Image v1.13, .zip" which actually resets the OS (Windows Embedded) for the MC Pro. After resetting this OS you need to re-install the application which runs the MC PRO: EUCONMC_3.6.1_Win.zip , which you'll also find on this website.
I've got quite some experience re-imaging my MC Pro (v1) so if you need help you can PM me.
