Please help! Activesync stuck on looking for changes

[lbulmer]

Yesterday I downloaded trial software (CompanionLink) that was supposed to sync my PC PIM (Time & Chaos) directly with my phone (HTC Mogul). It didn't work, so I uninstalled it. Now I can't even use activesync. It just sticks on "looking for changes." It's connected to the phone, as I can explore fine. I've deleted the partnership on both the PC and the phone; I've deleted the folder with the phone's name in My Documents; I've uninstalled and reinstalled both activesync and Outlook. I've even changed the USB cable to a different slot in the computer. All to no avail.

Is there anything else I can try short of doing a hard reset on the phone?
