Installing Halion 4 Mac problems

Hi everyone,

I can’t post a new topic on the Halion 4 page (“new topic” doesn’t show there anymore) so I post it here.
Yesterday I received my new copy of Halion 4 and when I try to install it on my MacPro, the 1st DVD install well, then it asks for DVD 2 and when I insert that, it spits it out again all the time and nothing happens.
I don’t see any scratches or something like that on the DVD (it’s new of course)
I’m running MacOS 10.6.8 and Cubase 6.0.3
What can I do?
Any help is much appreciated.
Thanks in advance,
