The CSR uses an unsupported key size!

I am on a new V7R1 LPAR and setup the *SYSTEM SSL store about 1 month ago.
I saved the CSR data during the *SYSTEM store setup.

Then today I went to get my first CA SSL certificate for this machine and
am getting this message when I paste my CSR into the SSL providers website:

"The CSR uses an unsupported key size!"

Does anybody know how I can tell what key size was used for the CSR? I
tried putting it in a .cer file but that didn't work.

As a last resort, does anybody know how to do a full reset of the *SYSTEM
SSL store so I can go through the setup again?
