New Macbook and Pro Tools 9 Download
 

So I just purchased a new Macbook running OS X 10.7 Lion. I went to download Pro Tools 9 from my Avid account but every time I run the installer that I downloaded one of two error messages appear:

1. It does not recognize

or

2. The file is corrupt

I have downloaded and ran other installers without issues.

Any advice, suggestions or fixes on the issue would be greatly appreciated.
