I can install my module, but I can't test it. VS2010 & XP pro sp3

The exception I get includes the text:
"It is an error to use a section registered as allowDefinition="MachineToApplication' behyond application elvel. This error can be acaused by a virtual directory not being configured as an application
in IIS.

I configured the web settings in the project, creating the virutal directory for http://localhost/dnndev/DesktopModules/Guestbook. It is set up as an application - No change. According to the book I should set up the virtual directory http://localhost/dnndev - but I can't use that is that is the direcotory for my dev instance of DNN and is already set up.

Any ideas what I am doing wrong???

Never mind. Looks like it was a misspelling in the IIS setup.
Off to the next error... ;)
