I get an error every time I try to install this game on my macbook. Anyone else have this problem. Also does anyone know how to fix this?

We'll need to know a bit more information before we can help you fix the problem.

What was the error message?
What did you do when you received the error?

Okay... I hate to ask this, but did you drag it out of the mounted image file and into your Applications folder? (Or anywhere else for that matter)
