Performance Advisor for Windchill - Not Updating

Curious if anyone else is having problems with the Performance Advisor for Windchill site not updating regularly.  The Creo site seems fine but the Windchill site hasn't updated in over 8 days for one of my servers and 5 days for another.

I opened a case a week ago with tech support but still haven't heard back on the cause.  Yes, I've confirmed that data from three different Windchill systems is being sent (at least it's present in the sent directory.)
