Q: Installing Logic Pro without disk install disk.

Hello, can anyone help me please?

I have logic pro 9, purchased it in 2010 from the apple store in southampton uk. I have all the disks bar the first install disk, i think my one year old has hidden it somewhere! I recently upgraded to the latest macbook pro without a disk drive, so I guess I can download the software from the apple store?

However, I can't remember what email address I used to register the software! So I added all of the as secondary addresses I have to my apple profile. Hoping this would pick it the purchase in the app store. Sadly not!

I still have the box and instruction including the serial key that of course was registered in my name, so would apple be able to get this the purchase liked to my apple account?

Or is there a different solution?
