Vista Sync help please!!!

[katrina2475]

I just got my new Mogul today and I can't get it to synch with my computer. I am running Vista. According to the manual, when I plug in my Mogul via USB, Windows Mobile Device Device Center is supposed to launch. It doesn't launch. When I double click on the program to open it manually, it just give me a menu of the type of connections it will allow and then I can click OK or cancel. When I click OK, the window closes but nothing happens. When I browse "My Computer" I can see the Pocket PC so I know the connection is there. Has anyone had this happen? HELP!
