Weird error when trying to launch mod

[Eugene1982]

I just installed the latest version of the orange box source code. At first it would not copy my dlls across to the SourceMods folder so after removing the checks for existing dlls in the custom build step and just running the copy command it copied them across.

The problem now is that when I try to run it it comes up with an error saying "client.dll is not a valid Windows image". I have never seen this problem before and have no idea what could be causing it. Does anybody have any insight here?

I haven't really touched the code except to fix the two errors which stop it from compiling in the first place (untouched code).

Use this one as a start?

Try doing a full rebuild.

The full rebuild didn't work, I have tried both debug and release builds. My mod is multiplayer so the OB developers kit won't work for me.
