BTYahoo internet probs

Bloody used their upgrade thing the other day and now i cant login direct, also gave me a shitty beta mail thing which was a bugger to use but at least had a button to revert to old one.

Has anyone else had this prob. I have had to use a second connection wizard and although i have set this as default its still using the other so ahving to do it manually.

Any help would be appreciated please as its not recognising my sign in

cheers
