So here's what I got all...an image of a laptop running Windows 7 64 bit...image was captured using DumpIt in an admin console:

Running "python vol.py -f ~/Forensics/FMCCOMBS-20141203-153133.raw --profile Win7SP1x64 pslist"

gets me:

And that's it.  Any hints on just why this isn't showing any processes?  Volatility version is 2.4 running on Ubuntu 14 64 bit.  Thank you.
