i've seen a couple posts about content installs gone wrong recently - open a ticket w/ support...
I noted that the PCI compliance package is 7.4.5.C1.398
I am setting this up under OM/RSCD version 7.4.6
Do I need to be running 7.4.5?
The release notes are not clear on this.
7.4.5 stuff should import ok into 7.4.6, but there is a 7.4.6 release of content if you go into the KB / Toolkits. try that version.
