On my DNN 3.1.1 I have module GalleryPA_3.00.10 installed and when i try to install Gallery_03.00.11 I have this error:

StartJob Registering DesktopModule Info Registering Definitions Failure ExceptionSystem.Data.SqlClient.SqlException: Violation of UNIQUE KEY constraint 'IX_ModuleDefinitions'.

I have DNN 3.1.1 with MSDE database on the same Win2k3 Server. direct database access.

Okay, you got me wondering, why would NOT uninstall it from the module definition menu?  I ask this mostly because my Gallery install stopped working in the beginning of November, and I've done lots to try to get it working again.  I've uninstalled it (via that menu) and re-installed it numerous times, and at least once I remember seeing it listed twice, so I uninstalled both instances before installing the module again.

So how badly did I break it if we're not supposed to uninstall it that way?
