Hiya, First off, I should probably say sorry that you picked quite an unstable time to play with volatility, as we've been actively working on the profile area, and the way that profiles are registered. Firstly, could you please update to the latest version (r493), and then trying running volatility with "-d -d --info" to enable verbose debugging. That may give you some debugging messages at the very start which could help in tracking down the problem, and will drop you into a debugging shell from which you should be able to type "bt" to get a backtrace and see any python exceptions that might be causing the code not to register. Please note that creating a new profile is not enough for all the plugins to start working with the new operating system. Vista support is currently very basic, although we are in the process of improving it. If you'd like to help in making and testing new profiles, you might want to mention it on the vol-dev mailing list and/or join the IRC channel, since this is definitely a developer task, rather than anything that should concern users of volatility...
