I've installed the free version of Kentico on my home computer so I could play around with it on the weekends. However, I cannot add or modify any of the files in Visual Studio. Every time I try, it tells me that access is denied.

When I add files outside of VS, it works just fine, though. Is this a problem with my security settings on my windows account, or is this a problem with VS? Or, is modifying the website in VS not something you can do in the free version of Kentico?
