Mesh displayed as dots I've imported a file and it seems corrupted, it in not due to Blender.
But I wonder if this "corrupted" mesh is still usable or not?
Originally, it was a haircut.

When I switch to edit mode, nothing is shown and I cant use "make edge/face".
It says "more vertices are needed".

here is the file: http://www.mediafire.com/download/5sk6acagdbu7ea0/untitled.zip



EDIT: In fact,  the problem can't be solved in Blender itself, as the tool used to import/export the .m2 file will mess up the result in-game, even if it looks ok in Blender.
You are in edge select mode, this is why you can not select single vertices:



Click the leftmost of the marked buttons, then you can select vertices again.
