Canon S230/Ixus V³ won't connect with XP system

My Canon S230/Ixus V³ gives me this message when I try and click on
Camera | My Camera Settings in ZoomBrowser (v4.6.1.35):

Unable to detect camera having My Camera setting capability.
Please check the following:
- Is a camera connected that supports My Camera settings?
- Is the connection implemented with an appropriate communications mode?

The camera mode Communication is set to Normal. Should I use PTP?

Using WinXP Pro with 768MB Ram. I can get the new pictures from the
camera connected with the USB lead, but it seems only when I click on My
Camera settings that I get this error.
I have been to
http://consumer.usa.canon.com/ir/con...4#New%20Window
to get the latest software so am wondering if I need to update anything
else?
Thanks
