namd-1: Fatal Error: Unable to Open CHARMM Parameter File

Hello NAMD Community,

I am new to the NAMD software, and have been working through the tutorials
on the website. Unfortunately, I cannot seem to run the tutorial simulation.
When I run it in a Terminal window, I get the following message:

Processor 0 Exiting: Called CmiAbort
Reason: Fatal Error: Unable To Open CHARMM Parameter File
../common/par_all27 _prot_lipid.inp

I have tried editing the path in Environment Variables and downloading the
file again from the website. I have also checked to make sure the path name
is correct and the file is placed in the correct location. The
configuration file is properly set-up, as well. I am using the software on
a Windows 7 PC.

Does anyone have any suggestions or tips as to how to resolve this problem?
I appreciate your time and consideration.
