The Skull Sequencer AddIn and the Skull Output Plugin have both been updated and should now be able to work on both 32 bit and 64 bit systems.
The Skull Sequencer AddIn no longer uses DirectX, it uses SlimDX. The runtime for this will need to be installed in order for it to work. I've included a link to the download to the install of the runtime.

Both the AddIn and the Plugin can be downloaded at http://ctm.maloneylights.com/downloads/.

I'd also like to thank Maffeirw for taking the time to test everything for me.

Enjoy, and let me know how you make out!
