But i cannot get anything to show up on the display. when i open up Device Manager, I see the 634 display in tthe usb section but not in the COM section. How can i fix this problem.

It should show up under "Ports" as a "Crystalfontz ...."

If it doesnt, try running the "Add device wizard". It should find it, and ask for the driver location.

Use the com port speed of "19200".

Also make sure both of the little switches on the back of the LCD are on (in the up position).
