Updated to Pervasive PSQL v9 SP3 on the server, and tried to run the PCC from my workstation (still on client SP2--readme indicates I could run with that). So PCC did not load, generated a bunch of Java errors to a log.  Decided to update to the client with SP3.  Same problems, however.  Workstation is XP sp2 all updates and the latest version of JRE 6 update 17.  Not being blocked by the FW.  It appears to be a java issue, but I can't seem to find much on the Pervasive sight.   Anybody have any links or URLs that they can share with me to troubleshoot?
