Project Templates problem with Database Professionals Add-on

I use Visual Studio 2005 Team Suite on Windows XP SP2 Korean.
I installed [Visual Studio 2005 Team Edition for Database Professionals Add-on]
And I changed [International Settings Language] from [English] to [Same as Microsoft Windows] (in this case, Korean)
After that, All project templates for Visual C#, Visual Basic, and Visual J# are gone.


Set VS2005 Language Option to English
Tools > Options > International Settings > Language: English
