I'm only your peer. I've asked the ICE and Photosynth folks to reply to you, so hopefully you'll hear from them. http://twitter.com/natelawrence/status/312768220312510465
In the meantime, if you just need the panorama for your project, I'd be happy to stitch it for you on my computer and upload a copy to my account until you can find out what's causing ICE to crash on your computer. (I think it might be running out of RAM.)
If you want me to go ahead and do this, just upload your input photos to SkyDrive (be sure to uncheck the default option to shrink the images at the top of the upload list) and share the folder with me at firstname.lastname@example.org.
