Hi Aaron,
I agree with Ingrid that these scripting errors don't make sense with the raster to polygon tool you are running, which indicates a potential issue with Python running behind the scenes.
I'd try uninstalling and reinstalling Arc on your computer to see if you can work out the glitches. If you do this - let me email you a new EVA (authorization) to use and instructions for a digital download.
This might sound like a pain~ but you still have Lab 10, and it would be great if we could get this worked out so you could continue to use your license for the next year without issues like this!
Let me know. I'll be in my office within a couple hours and can get the EVA for you right away.
