Isync (tiger) Quits Trying to Sync Sony Ericsson K700i


I'm running Mac OS X 10.4.2 and have just installed a new D-Link DBT 120 Bluetooth adapter, in order to sync with my new Sony Ericsson K700i phone.

The Bluetooth itself all works fine - I can browse the phone's files on the Mac, exchange files and so on, but there's a problem with iSync. I launch it, it sees the phone OK and opens up to let me set the options, but when I click the Big Button there's a brief pause and it quits. I've tried different combinations of contacts and calendars on and off, I've also tried restarting, all to no avail.

Any ideas? Oh, and I'm not running APE, which I gather can cause problems.
