1. Clean installation on a standalone Windows Vista workstation
2. Created new Profile in DDT
3. Created a new connection to my SQLExpress instance.
4. Created new Database in DDT
5. Attempted to add a new table to the database in DDT and got the error

Hope this helps.

Based off of your previous post there is no way to reproduce the problem...at least on my side.  I need to know more detail about your structure.  The details that you provided describe the most simple functionality of the DDT and does not contain any information regarding your structures.
