I believe somewhere in one of the harddrives there's a program that generates an x-list and basically terminates all programs that match up to the ones on the x-list. I doubt there's anything you can do about it short of hacking the computer, so...
If you only want to play the game, on the other hand, without saving, then you can just download the swf file and put it on a flash drive.
EDIT: Actually, I just tried, and I think the swf file still lets you access your account and play the game without even needing the website, so long as you are connected to the internet. I could be wrong of course, but hey, you can always give it a try.
