I am having problems where HTC Sync on my PC will not recognize my device. I have used multiple versions of HTC Sync. I have tried to sync via VPN and via direct LAN connection. When it tries to connect, I get the error msg on the device that says Unable to find HTC Sync on your PC. I disconnect all cables, exit out of HTC Sync on the PC, then open HTC Sync, reconnect the cables....NOTHING!!! This sync WAS working previously when I first got the device on this past Thursday but over the last 2 days I have been having no success. I have deleted all calendar and contacts via Settings -> Manage Applications. At this point, I am tempted to try Companion Link unless someone can help me here. By the way, I am trying to sync with Lotus Notes 8.5 calendar and contacts.
