Hey Kirupians

I’m trying to use one of the many physics engines for AS3, but no matter which one I use, they have a Vector class. Somehow my Flash CS5 doesn’t want this class, and tells me that I use an incorrect number of arguments, and it expected 0.

I think the error is because of the built-in Vector class, being annoying, and overriding the one I’m trying to use. How can I resolve this?
