Dear Nitin,
I'm attaching a recently modified version of NAMDenergy that uses amber
files instead of charmm; please find it attached to that email; just
source it prior to opening the namdenergy plugin during your vmd
session. The presence of an amber-based topology is automatically
detected. Please let me know if you have any problems. This capability
will be included in the next release of vmd 1.8.6.

I will also note that just in general, you should upgrade to vmd 1.8.5
and namd2.6 to get the best results with this plugin.
