Windows Mobile Device Center is not working?

My Windows Mobile Device Center is not working, I am connecting a Dell Axim X51 PDA to a Lenovo Windows 8 (new windows) Computer. Every time I try to disconnect and reconnect the USB cord, it does not keep it recognized. I keep trying again and again for about 2-8 minutes, but it still does not work. Is there any way to have the PDA get connected to Windows Mobile Device?

The PDA is bought from a third party seller on a third party website.

I need help on this, I need PDA to Windows Mobile connection worked by tonight.

Please and thank god, help me.
PDA has a solid orange screen.
