@lolcat556(View Post) if it worked, the game will pause for half a second while the script downloads, and then yes you should see a new icon appear above the walls menusection.
Then just click that and click the 'online' button.
Can't guarantee it is the latest version but I had it in my dropbox and it says 90.2
Also, that one line of code on the last page just downloads a file using luasocket, which really can't possibly fail. Running that and restarting TPT will get you the script manager and access to about 50 scripts (with the ability to add your own manually).
