Installing Unity 3.2

I'm just trying to install the free version of Unity 3.2 from the Unity website. I'm running Snow Leopard on an iMac.

unity-3.2.0.dmg downloads fine. When I try to open it, however, I get an "not recognized" error. Has anyone ever encountered this error?

It sounds like your download was interrupted. Download it again, I just downloaded and installed it on Snow Leopard without a problem.
