Global error processing your request

We are in the real estate business and utilize a database driven system of allowing users to save their search criteria which we in turn alert them with properties that fall within their criteria. Similarly, we also allow sellers to create a "saved buyer alert" which will notify these sellers of new buyers who fall within ther buyer alert criteria established by the seller.

All was working well until we moved/upgraded to a larger server at Slicehost. Whenver atempting to add or edit a saved search or saved alert, we receive the error message *There was a global error processing your request*.

Any advice??
