Hi,
  I would guess that you are running into the 32-bit
memory addressing limit of the Windows version of VMD.

As Axel has already pointed out, there isn't nearly enough information
in the email below to determine what your real problem is.
>From the little information you provided, my guess is that you're using
more than 2GB of RAM, which is the limit for a normal 32-bit process
under Windows.

Cheers,
