|I wish I could help you with this.|
I have something to use this article for recovery: http://www.ai.viewertool.com/
Here's some 20/20 hindsight advice...and I speak from experience... save, save, save... and backup your files whenever you are working on something where there's alot of time involved to recreate. Like I said I learned the hard way... I lost 4 hrs worth of recreating a very complex logo.
I'll ask around some people I know to see if they know of something. I'll let you know if I come up with something.
