Afino, I've uploaded a new set of files
here. I didn't feel like figuring out which files you definitely needed new versions of and which you could leave alone. So just overwrite them all.
If all goes as I hope, you will either get a pop up error message, or you will get a file written to your C:\ called "devTrackerErrors.txt". Open that sucker up and let me know what it says.
You'll almost definitely get past the players.csv this time, as the errors are getting caught and bypassed. This doesn't mean the program will work, because by bypassing the errors, it's not writing the .csv files to the necessary tables the program uses. But at least you'll get to see the interface! (hopefully)
Good luck again!
