  I sent a reply to your other email on this topic yesterday, but
the mail must have bounced or gotten delayed somehow. I was able to load
and display your DX file without any problems. Have you tried just
loading the DX file all by itself? If you need more help with
coloring by potential, follow the steps in this short tutorial, and/or
try loading the example data I have provided with it:

The example data there is from ABPS, but it will work with your DX
files as well.

After loading the DX file I got the following information that I have posted below, but I could not visualize the molecule with its potential. I am also sending the DX file as attachment. Would you please, go through this and give me some suggestion how to render the electrostaic potential. Eagerly waiting for your reply and help. One more thing I am using Window-XP (32-bit, 512mb RAM) not Unix and Linux.
