Unable to search on existing Campaigns and Mail Forms

Hello,

We upgraded from 4.0 to 7.0 SP2.

Using the WebUI, I am able to search for existing Marketing Plans but cannot search on criteria for Campaigns or Mail Forms.

If I enter no search criteria on Campaigns I am able to retrieve a bunch of existing Campaigns. I cannot search any Mail forms with or without criteria.

Any help would be most appreciated.

Thank you
