Is it legal to download games I own?

[Loaf]

My brother and I bought a game in like, '06 or '07. It was one of my favorite games. I just plugged in my old hard drive from a broken laptop I used to play the game back then using a SATA / IDE to USB 2.0 cable but sadly I must have uninstalled it as it wasn't there. My brother since moved and lives at the other end of the country, to my knowledge the disc became scratched or broken since then and is useless, as I asked him to send it and he told me he couldn't for such reasons. Since we did pay for the game, can I legally download an ISO copy of it to play the game since I don't believe its sold anymore (it was an old Starwars game) and even so I'd be kind of pissed to have to purchase it again. I think I might have purchase proof somewhere (if not for the date stamp of the game having been uninstalled on my old hard drive). I know its legal to create backups, but from memory I think I read that was only if you directly copy the disc while its in good condition... not using someone else's copy long after yours was rendered useless. I would have backed up but at the time didn't have the know-how or the tools to do it (copy protection derp). HALPPP. EDIT: I actually just found a retailer online in my country that can send it new, but would still like to know the answer to this question.
