What ever i do i cannot get to include a file and load it at runtime?

Its a .obj file and im trying to laod it into the mesh obj, this works all fine if i load it normally from disk. If i try to do it by adding it as a binary file in data elements, it simply doesnt load.

I add the path in Data Elements, at the start of the frame I Extract Binary File (SAME PATH AS IN DATA ELEMENTS), and then i load mesh using BinFileTempName$(SAME PATH AS IN DATA ELEMENTS). I then Build my application and then rename the original .obj file to make sure it doesnt laod it from there, and when i run no mesh is loaded?

The only reason im trying to do this is because I want to protect my files.
