PP2010 installed without incident on my intel iMac running 10.5

I have a new Mac Pro running 10.6 and PP2010 will not finish the content installation. It stops on problematic files like leg wraps. I rebooted and tried again. Then downloaded the content installer again. This time it passed that file but stopped at another file and still won't install. I went to SM forums and searched but found nothing relative. Can someone please tell me what to do next?
