Closed Unassigned: can't save certificate [168]

I installed WPP. I sorted out the server/console version issue. The next step is a set a certificate. I click "Generate the certificate" and it tells me it was successful. However, the "Save the certificate" button is not available.

I'm running WPP from a 64-bit Windows 7 computer. WSUS runs on a Server 2003 R2 Standard Edition SP2 computer.
