I put just the numbers and same password that get me into my IB account.
Everything is the same in both accts. and it does not recognise.
The BA acct. with an address that is still different is fine, I can load that one in Avios and it comes up with how many points I have, ( but that's as far as I go )
I'll try again in the morning and then E-mail them, must be something wrong at there end. can't understand why I can get BA logged in but not IB..

thanks for trying
