This issue has come up before. I suggest you post a message here and share your experiences. Hopefully, you can work together to find a solution. It's hard for us to help when we can't reproduce the problem.

I finally figured out what I was doing wrong.  I had the same error, so maybe you are making the same mistake.

Like you, I followed the instructions to the letter.  Never having used this product before this was a must!  Well what I figured out was using the examples you create a folder in the root of c:\.  Install  the software in it, set it as a virtual host location.  Then you go to visual studio and create a new web site.  Visual creates this site in your My Documents/visual studio 2005/websites directory by default.  Your web.config file does not exist in this directory, and your virtual location does not point here.

I simply renamed the release.config file in my documents directory and changed my virtual host location and all worked.

Maybe you have the same problem.
