No cubes can be found error

In the data panel of the report designer component, every time I try to create or modify an MDX statement, I'm now getting a "No cubes can be found. (Microsoft.AnalysisServices.Controls)" error. Works fine on the Layout and Preview tabs. Just all of a sudden appeared. Working fine against relational sources. As a warning to all, Reporting Services and Analysis Services is definitely not a marriage made in heaven. Proceed with caution.I'm going to have to learn to delete my profile everytime something strange happens with SQL 2005. Somehow, my profile on my primary development machine was corrupted again.
