I see the problem immediately. The VMK home page tells us that we
need to start at the shipwreck quest area. Here is the progression I took
for the Tomorrowland Quests:
1. Shipwreck quest. Walk towards where the bottom left of the screen until the "exit" icon appears, which will take you to the second level. Walk to the machine and you'll see a hand icon when you move your mouse over it. Click the machine to receive the Quest, and you're off! Be sure to wear each magic pin as you win a quest.
2. When you get the Dive pin after completing that Quest, go to the Autopia Quest track. There's a yellow machine that gives you the quest. Be sure to return when you want to complete the other three quests. I did both the blue and pink quests at once.
3. When you have a car pin, use the magic on the Autopia Quest Track to pick up the gas cans. After you pick up a few of them, you will get your Autopia license. Don't forget to put on the license pin, because you'll need it to do the Space quest.
4. By now, you should have at least the Dive pin, a Car pin (or more cars if you completed more than one Autopia quest) and the License pin. Go to the Space Quest deck and click on the big computer console to get that quest.
The Space suit pin is the prize for winning.
5. There are two quests that you can play that aren't part of Tomorrowland, so you can play them at any time. Animated Trivia and 50th Mickeys.
There are items you need in the quests that many people wouldn't know about. The two most surprising things I needed: Bat Magic pin and Everest outfit . You can't get the Green pin on Autopia Quest 4 without the bat magic, and I can't remember which quest needed the Everest suit.
