SCUP 2011 fails at publishing updates

I'm attempting to set up SCUP 2011 on a 2012 Datacenter edition virtual machine with SCCM 2012 SP1 and WSUS 6.2.9200.16384 previously installed.

As a test, I'm attempting to deploy the latest Java update MSI following the steps in this link: http://www.techygeekshome.co.uk/2013/04/java-client-updates-deployment-using.html
It's failing when publishing full content. Publishing Metadata works.

During the SCUP setup, I'd imported our domain cert (2048bit from GoDaddy), and set that cert up in Trusted Root Certs, Trusted Publishers, & WSUS, and enabled GPO to accept it. I have not installed the WSUS 3.0 SP2 hotfix, as it appers to not be needed/compatible (error when attempting to install it screenshot
I'm getting the following series of errors in the SCUP.log. I don't understand why some times are timestamped with a date of 1/1/1601 (see bold), and have unchecked the setting in SCUP options - add timestamp when signing updates. (neither way works.)

Everything I've googled seems to point to certificate issues or installing the hotfix, but I don't see how that could be the problem.

FYI, I believe I've resolved this myself.
Changing the Domain cert to a SCUP generated WSUS self-signed cert and adding it to the proper places (Trusted Root, Trusted Publishers) has allowed me to publish without errors.
