it's not working because
he didn't do it right: >> Attempting to change display settings to fullscreen 800x600x32@60Hz...he needs to not put it in fullscreen
have him do this:
1: download this file:
http://66.206.83.240:8000/main.cs2: go into his steam library, right click on blockland, and click "properties"
3: locate the "browse local content" button and click it
4: go to the "base" directory
5: move the main.cs he downloaded into that directory
6: launch blockland
provided he never gets rid of that file, he should be fine from then on.
