Internet explorer 7-problem with capitalone website/cookies disabl

My desktop has windows xp, and I just installed IE 7. I am having a problem
accessing www.capitalone.com, a website I go to every month to pay my bill.
(This is before and after installing IE 7) The homepage loads, but when I
click the link to login, I get a Cookies disabled page. This is what it
says:

Cookies disabled
This could be caused by one of the following reasons:

I called capital one tech support and they couldn't figure it out, they had
me delete the temporary internet files, cookies and history and nothing
changed. In internet options, under security I tried accessing the login
site with it set at medium-high and medium, nothing. Under Privacy I tried
with the each setting from accept all cookies, to medium high and no luck.
Each time I closed the IE window and opened another one to retry. I have no
idea what else to do and cannot find any solutions online. I am not having
any problems with other websites similar to this, I paid all my other bills
online with no problems.

Any solutions or ideas out there???
Thanks so much!
