Help with game installation!

[Captain.Bar]

Hi everyone! I think I made a mistake when I installed the game.
My boyfriend, who downloaded it too, says an icon appeared on his desk and he enters the game from there everyday. But when I downloaded it, no icon appeared and no "Pirates of the Caribbean" folder is in my computer, although, I managed to play the game, entering the page and going to the inicial page, from where I downloaded it the first time.
The problem is this: I tried to enter it a minute ago, and the game started to download again, immediately. What can I do? Did I make a mistake in the installation? No setup folder or archive appeared the first time.
I'll be really grateful if you gave me an answer.
Thanks, mates!
