New MYT won't connect to computer

HI All,

I just received my new MYT yesterday. Installed the software and driver and the mount does not show up in the device managers(windows7). Tried a different usb cable same results. Moved to the computer where my Paramount MX is, changed to a Myt and still no listing for it in the drop down list for the com ports. Disconnected the MYT and switched back to the MX and immediately connected. So I would guess the I have a Bad MKS 5000 board. I am open to any suggestions on any thing else to try. Also the mount homes and operates from the hand pad fine.

Thanks

Jim Boardman
