Yea both of those don't work. I downloaded the older version and that works just fineDo you have the same problem on build 1.0.4b? Looks like a python interpreter bug. There are several explanations, and you should rule out some bizarre hardware conflict first. Other than deleting the files and re-extracting, which is the simplest, create a virtual machine with some quick Linux distro, for example with VirtualBox software, and download the Linux FET version. Let me know how it went.
