Visual Studio 2008 SP1 with GDR2 - DBMDL could not be created

I get the following 开发者_JAVA技巧dialog when I try to load any DB project in Visual Studio.

There is nothing else locking it, nor are the permissions on that specific folder restrictive. This used to work, but I re-installed VS2008, then Sp1, a few hot fixes and GDR2.

Now, when I try to load any DB project, I get the dialog above.

When I open VS, I get the following dialog; it's different, but message is the same..

Try opening Visual Studio as Administrator.

You can check locks on files by using process explorer: http://windowsxp.mvps.org/processlock.htm
