We will be posting a release in the next few days that supports SQL Server 2008 in every respect from the design-time all the way through to the DDT.  The problem has to do with the SMO engine supporting 2008.  We have updated our references and made some changes to fully support 2008 and below.

Qwerty, adding to Aaron's reply, also do a search in the forum for SQL2008 where you may find some work arounds using MS-SQL2008.

I am not sure SQL Server 2008 is fully supported yet.
