It looks like there's an issue with the setnet.py file, which is still listed as a text file. My hunch is that it still has the txt extension, and windows has the file name as setnet.py.txt
You might try using the cmd prompt to rename the file with the ren command. With the original setnet file (setnet.txt) in your folder, type the following:
ren setnet.txt setnet.py
Hope that's the issue and helps.
