Activesync quit working
 

I have been using Active Sync 4.2 with no problems for months (WM 5.0 & xp).
Suddenly it stopped working. It sees my device, but it says it cannot
establish a connections. Ihave already done the following:

1. Done each item on the trouble shooter checklist (including checking to
make sure usb ok was selected on the device and on the pc;

2. Checked the firewall and anti virus settings I even disabled them to make
sure;

3. Uninsalled Active Sync COMPLETELY, including deleting the left over file
in Program files, and then reinstalled (I did this 3Xs, twice with 4.5 beta)

4. I did system restore twice to dates prior to last successful sync;

5. I did a soft restart on my PPC and rebooted the PC each time.

HELP!!
