I'm Martin and have had a number of HTC products in the past and now have moved over from Windows Mobile to Android. Like the phone but the Sync Software is problematic. Installed HCT Sync on Monday on my Widnwos XP Home edition Desktop. Worked fine, synced fine. Still mounts. But yesterday stopped syncing even though it still mounts and still connects via the usb. Contacted HTC this morning and spent an hour or so on the phone following their instructions. In the end they said that they cannot help as it must be something wrong with my pc. Have uninstalled HTC Sync and reinstalled. (Trying various editions.) Have cleared the registry using "CCleaner". Have disabled windows startup programs. Plus various other experiments. Nothing works. Any suggestions?
