cannot see Logic Pro 9 in app store purchases

Hi all,

in late 2011 I got my freshly bought MacBook Pro 15 together with Logic Pro 9 Studio (box) from school.

I registered Logic on my name and I am the owner of the macbook and the app (since i paid for it).

Problem is that Logic Pro 9 Studio (together with all the additional apps) never appeared on the Purchased Apps list in my App Store.

Since I'm planing to buy a new mac I'd like very much to have this purchase on my list so I can download everything when needed.

Any solution for this?! Anyone experienced this issue?!

Best,

Alex
