Hey everyone, I've just upgraded to Sonar X2 Producer via the free upgrade link. I've downloaded part 1-4, but 5 minutes in the installation it's asking for disk 4. It says it cannot be located, even though it was downloaded and saved. Does anyone have a solution to this? I'm wondering whether I actually have to install literally everything (8 items or so) for this to work? I would really appreciate it. Thank you.
