Before installing Mavericks, I erased HardDisk. iLife suite was pre-installed. I tried to re-download them MacAppStore. But there is only purchasing option. I no longer use the Apple ID which I was using when I made the purchase. What to do?
You could always call Apple. If you can verify you are the legal owner of the old Apple ID and the current one; they 'might' be able to transfer the purchases.
Have all the info for the old ID ready.
if that fails then you have no choice but to re-purchase with the new ID
