I have the same issue. WMDC worked 11/26/2007, now it does not. I have an
AT&T 8525 with WM 6.0. I tried reloading WMDC, I uninstalled at least 10
times, turned off firewalls, disconnected from internet, unchecked advance
networking and basically have spent 15 hours online doing every imaginable
permeatation of posted fixes including the simple one on the WM site. My
phone is recognized in device manager but that is it. WMDC almost boots but
stops (YES THE PHONE IS ATTACHED), synch center sees phone as guset but will
not let me attach, blue tooth sees phone, links and then does nothing else.
My HTC driver on the device matches the version of WMDC. I have run "check
for updates" no less than 50 times. I have added nothing to my phone since
last synch. I have deleted the partnership on the phone side. PLEASE HELP!
