We spent weeks trying to debug an issue where we could not get the data cards to load when saving a new SW file.  We kept thinking we had some sort of an issue with how we had EPDM configured but it came down to SW2009 SP5.0 and SP5.1.  We are running EPDM 2010 SP3.0.   When running any of the older SP in 2009 data cards loaded evertime with no issues.   SW 2010 also had no issues.  We have dicided to just go ahead and plan to upgrade everyone to SW2010.

Hopefully this saves someone out there some headaches.  I would be curious if anyone else has ran accross this issue.
