how can you buy/install lion????

Hello:

Your question is a bit vague (no information about what you are running).

To buy it, I would contact an Apple store.

I have the same problem. Ive upgraded to 10.8, but now I cant download 10.7 from the Mac App store. Pretty bad since I've paid for it just a year ago. I don't understand how Apple can deny me access to my own property. I can see 10.7 under "purchased," but when I hit "download," I'm told that I can't because I got 10.8. 😟
