I've seen a few posts from you about this issue, and while this may be a stupid question, you do realize you have to compile the code you get from github.mangos before you will get a bin folder, along with relamd.exe and mangosd.exe, yes? Those files are not precompiled when you clone a GIT repository, you need to open the solution in Visual Studio (or however you choose to compile) and build it.
Forgive me if this is what you are doing and you are experiencing another error, I'm just trying to troubleshoot.
