If he didn't buy the game, he wouldn't be able to select internet game at all.
Alright, start Blockland, try to run an internet server, let it break. Then, right click on the blockland icon on the desktop go to properties, and find the "find target" button. Then, in that folder that comes up, locate the "console.log" file. (It may just appear to be a text file called "console.") Now, either attach that file to your next post, or open it and copy all the text in the file, and paste it into your next post.
