I've been frustrated trying to solve this.

Whether I am syncing with cable or through bluetooth, 8 seconds into the hotsync it closes and I get a message on the computer screen that the Conduit Manager has encountered a problem and my 650 reboots.

Clicking on the "More information" button of the error notice leads to pages of computer lines and begins with Error Signature: Exception: EXC_BAD_ACCESS
and ends with this:
Microsoft Application Information:
Error Reporting UUID: FD1A9E67-37A4-11DB-9E31-00145104772E
Time from launch: 0 hours, 0 minutes, 3 seconds

Has anyone encoutered this?
