I'm having serious trouble with HTC Sync. I have been fighting with it for the past three days. I'm running Vista Home Premium SP2. I have tried HTC Sync 3.0 and the latest version from the HTC support page. As soon as I plug my phone into my laptop (HTC Sync as default connection) with HTC Sync open my phone finds it connects then disconnects within five seconds or less and closes HTC Sync. I have emailed HTC's support team and have tried everything they have told me to do down to the period. I have also tried going to AT&T and seeing if they might have answers but they were as clueless as I am. If anyone has any insight on how to get this fixed I'd love to hear it. Any help in the matter would be greatly appreciated. Thanks.
