Connecting to BT Openworld

Having successfully used an earlier version than the current SMART FTP to upload my website details to my BT Openworld website, I have now lost that connection after having had to restore my PC. I can't remember what maps to what in the 'Remote browser window' (particularly host / path / username). I know it should be easy but:-

a) I'm a bit thick and
there is no longer anything at all about any of this that I can find under the BT or BTYahoo websites

I have the old anonymous password and address from the old SMART connection but am lost with how this maps and having spent far too long on it, am now losing the will to live!

Any help gratefully received. I found SMART absolutely brilliant and just want to get back to where I was!

Thanks in advance!
