​I don't know. It was clearly the most obvious problem, but there too many
problems that I know about (and probably more that I don't) to say that
your files are problem-free. The only time I feel confident saying that
files do not have problems are when I've prepared them.

Also, I recommend you visit the tutorials --
In particular, the one about using VMD with Amber addresses precisely this
issue (and does more to help you use VMD successfully with Amber).
