Mobile Device Center Connect problems / Vista 64Bit

I am having trouble getting my nice new (and previous ) phone to connec
to Microsoft Windows Mobile Device Center.
I have Vista Ultimate 64bit and am trying to connect an HTC TyTN I
phone(using WindowsMobile 6)
Installed WMDC and Microsoft Windows Mobile Device Center 6.1 Drive
forVista (64-bit), if I switch the phone to Active Sync and connect th
USB cable I see the Gren Ball twisting for about 30sec, then it grey
out. Also when I plug in the USB lead if I look at System /Devic
Manager / Network Adapters, when I plug the USB lead in, Microsof
Windows Mobile Remote Adapter #2 appears, when I disconnect the USB lea
the Mobile Remote Adapter #2 disappeares.
So it seems that Vista is recognising the device OK, but the device i
just not being recognised by WMDC
I am using NOD32 Protection but have stopped that from starting an
still get the problem
Had exactly the same problem with my Mitac PDA on this machine

All help appreciate

Thanks E
