COMException when creating SSIS Package / DataSource

I'm running sql2000 and 2005 (RTM) side by side (and vs2003 and 2005 RTM). I want
to create a IntegrationServices project.
When i want to create a DataSource, i can specify the connection, but
when i click on finish the screen is not closed whatever info/name/etc.
i fill in. I can only cancel the dialog box.
When i add a new SSIS package i get this exception:
===================================
Error creating package (Microsoft Visual Studio)

Exception of type 'System.Runtime.InteropServices.COMException' was

Any idea what's causing this? ( i reinstalled SQL 2005/SSIS several
times)
Thanks

Do you use any third-party add-ins for Visual Studio?
Do you use source control integration with Visual Studio,
if yes - which source control provider?|||Yes. i'm using DevExpress CodeRush/Refactor... no source control integration.

Thanks

Marco|||Could you please try removing the DevExpress add-in and see if this fixes the situation? Looking at our code - we are simply notifying environment about new file, and some external code subscribed to this event reports failure, thus cancelling adding a new file. Since it does not happen normally, I suspect the DevExpress add-in causes this.

I'll try to get my hands on the DevExpress CodeRush/Refactor to check what's going on.|||Thanks!

Disabling fixed the problem.. I will send my errorreport also to DevExpress.
