i can't find mac os lion previously purchased
I purchased MacOs X Lion somewhile ago (maybe more than a year), and lately my computer HDD crashed.
I went and install snow leopard back again, and when I'm trying to find the MacOs Lion, it doesn't appear in the AppStore. Tried to install Mountain Lion, and says that my computer is not eligible for this update.
Please inform me how to proceed.
MacBook, Mac OS X (10.6.8)
