password problems

Anyone else been told to change their password to theie amex card? I just treid to log on and got a message that I had to change my password. I tried to, following their stated parameters and got a message that it wasn't valid.....

Just hanging on the phone to Amex, they say there was an update this am but it went swimmingly.

No it didn't.......[:#]

Yes, and new password was accepted fine [?]

Have just spent 30 mins on the phone, then husband came up with the fact that it might not be accepted if I had an '@' in the word - which I did. Smarty pants, I did a substitute and it worked fine - the net guy at MBNA hadn't thought of that.... me, I'm just glad I got it sorted!
