IE 7 cipher strength: 256bit

I'm trying to download a security cert to login in to a private "vendor" website. and the website gives me an CryptoCompatiblityError.
"Microsoft® security store Error: Required encryption strength not available.

Problem cause:

Your browser does not support the high-strength encryption required by this Web site. Please upgrade your encryption level here
"
My version of Windows Internet Explorer7 is 7.0.6000.16386
Cipher Strength: 256 bit

I've also tried it with Firefox and Opera... no luck. it worked fine before I upgraded from XP.

Any Suggestions?

Thanks,
Aaron
