Access 2007 beta & VS web developer incompatable?

[xz]

I'm doing a quick 2 step process to access a database, as outlined
here:

http://msdn2.microsoft.com/en-us/library/tw738475.aspx

I successfully point to my Access 2007 .MDB file.
But in the configure data source dialog, when I go to 'Query Builder' -
I immediately get an "Object Reference not set to an instance of an
object". Haven't written a single piece of code yet, and I've got
the framework (v2.0) installed.

Any ideas
