Thank you all, I got this resolved. I compared versions of everything btw the 2 computers, and since they had same versions of ruby and watir, I uninstalled all extra gems and reinstalled watir (along with the 15 or so gems it uses) on the computer that was not functional. I could not find the specific culprit, but now it all works...
