We've been telling you this over and over. If you're going to call the steps we already gave you unhelpful, then you won't be able to get into it. Stop flooding the boads with the same god damn topics.
Move your mouse over your Blockland shortcut. You see the button on the right (→) side of the mouse? Press it. A white menu will pop up. Move your mouse to the selection labeled "Properties." Now, press the button on the left (←) side of the mouse. There should be a few boxes with words and numbers in them. See the first box labeled "Target?" Move your mouse over that, click the left (←) button again, and then press the "End" key on your keyboard. Now, press the spacebar (the huge button at the bottom of your keyboard) and reach for the hyphen (-) key, press it, reach for the "m" key, press it, find the "o" key, press it, find the "d" key, press it, press the spacebar again, press the "e" key, then the "d" key, then the "i" key, then the "t" key, then the "o" key, then the "r" key (you should have successfully typed "-mod editor" into it). Move your mouse to the button labeled "Ok" at the bottom of the box. Press the left (←) mouse button. Now, move your mouse over the Blockland icon - which is a big letter B. Consecutively press the left (←) mouse button twice. When the game loads, move your mouse over "Start a game," then press the left (←) mouse button. Move your mouse over anything in the selection box, press the left (←) mouse button, then move your mouse to the "Launch Game" button, then press the left (←) mouse button. After the blue bar reaches the far right (→) side of the screen and you are now in full control of the game, reach for the F11 key, which is on the top-right corner of your keyboard.
If you still think wasn't detailed enough, then you're a moron.
