Allready got my first problems, hope you can answer my questions. :)

1. I can't open the project files. Is this because they are made in VS2005?
Error:


2. I can't run the demos in the bin directory.. My VS pops up with a debugging window saying an error 'System.IO.FileNotFoundException' has occurred.
3. Any idea how to include the engine in a C++ project? I've no idea how this is done in C#, and I don't see any headers/libraries (except for the bin map). I also noticed the C# projects use '..\..\Engine\HadddEngine.csproj', but I can't find that map (maybe it isn't needed, but hey, I can't know that :P ).

Thanks in advance. :)

*EDIT: I started to learn C#! Who knows, maybe I switch over. :P  

 Hey all!
First of all, engine looks real nice, good job  ;)

Second, is it possible to use this engine in C++? If yes, how?
Since I don't know C# and don't want to learn it. :P

Thanks in advance.
