Leyla,
  When you attempt to load the Charmm CRD file into VMD, you'll need
to manually specify the plugin type to VMD by selecting "COR" type
from the list of plugins. Unfortunately, both Charmm and AMBER use
"CRD" for various things and VMD doesn't presently have a way to guess
which one it actually is, so you need to help it by manually specifying
the plugin to use when you load it. Let us know if you still need help.
