Nokia 6310i Bluetooth Connection Problem

I seem to have fallen victim to a common Nokia Bluetooth problem.

Basically I cannot maintain the connection between my Nokia 6310i and my PC.

I am running Windows 2000Pro.(SP4), Nokia PC Suite ver. 4.88 and XTNDConnect
Blue Manager 3.1. The Bluetooth driver seems to be Windigo Systems, although
W2K reports both the driver date and driver version as "Not available".

My 6310i is running software V5.60 (which is the latest version).

Everything seems to have installed OK; the PC finds the Bluetooth dongle,
Blue manager finds the phone and the phone displays the connection request
(which I accept). The passcodes are entered OK, the phone displays 'Phone
connected', then, a couple of seconds later, the phone disconnects and I get
an unhelpful 'Unknown Error' message on the PC screen.

From reading previous posts, it seems that Nokia's PC Suite is the problem.
Should I use Blue Manager's Mphone management software instead? Or anything
else?

I shall have another go at resolving the problem soon, but in the meantime
does anyone have any experience of this problem, or any solutions that I
might try?

Is there a more recent version of XTNDConnect Blue Manager, or is Ver.3.1
the latest?

Any help appreciated.

TIA
