Actually I just managed to get around this problem by doing this quickfix.
You must be registered to see the links
It seems it was on the "restricted sites" tab most likely in the above video (as I tried it throughout the vid to see when it would run and it started going past the error/blocking only after the last step).
However, now I'm faced with yet another error because I tried to run the main .exe. Then I went into /lib/windows-i686 folder and launched it from there and it worked. (Might have worked without all the errors all along if I clicked the right pathway who knows).
Works now thx tho.
