We do not encourage using something that's illegal here. You'll have to contact who-ever you bought the CD from if you really bought it assuming you just bought it recently. Other than that, - I'd recommend buying a copy of GTA:SA that you can directly download. You'd just need to apply a downgrade patch and it would work. Most sites you buy from will let you download as many times as you need in case you accidentally delete it.
