Trying to get source code to launch but getting erros.

Hi, trying to get the source code to work for once (Arghhhhh) and I'm having some trouble. First does X64 mode even work? Because both it and X86 mode have different problems and I'm trying to decide which is the path of least resistance. and I guess X86 would be if X64 isn't even off the ground yet.

As for my X64 problems, Their mostly errors that I don't understand and can't find a lot of info for. those can't find the right version of SteaSDK, or some other thing... I thnik right now it's....
System.IO.FileNotFoundException was unhandled
Message: An unhandled exception of type 'System.IO.FileNotFoundException' occurred in Unknown Module.
Additional information: Could not load file or assembly 'SteamSDK, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.



And as for X86 it keeps telling me their are errors in classes that center around rendering. Right now it's giving me this error message:
Which I just realized is pointing a file that I deleted... so Imma look into that. (this is one of those, I've been working on this all night and cant think straight anymore so I'm a post this hear and hope something good happens while I sleep this off posts....)
and Visual studios puts me at line 101 of MyRenderProxy.cs Highlighting the line:
return m_render.CreateDevice(windowHandle, settingsToTry);
if that helps anything.

So I'm not super sure what to do here. thanks for any help in advance.
