Help - BT Anytime members!

[Masterplan]

Whilst surfing the Net yesterday, my home page (BT) stated that all BTinternet Anytime members (I am one such person) needs to download and upgrade their dial-up network. I clicked on the given link, and so my dial-up network and BT Anytime icon has changed. However, it has changed for the worse, as I cannot actually connect even though I double-click on the BT Anytime icon. It appears the 'phone number has changed - perhaps this is the reason.

Could any fellow BT Anytime members please tell me the actual 'phone number which is used to dial-up? I would be MOST grateful.
