I bought the 2nd edition of SA and wanted to install some new models for the guns such as the 45, Tec9, Ak47, so on and so on. The thing is that everytime I load up the save game, it stops loading midway. So I searched around the net looking for any solutions to this problem. I found the downgrade patch here, i installed it and now it just crashes midway. I am installing the mods right, but it seems that second edition GTA can't be downgraded. Is this true? I want to make sure so I won't keep uninstalling and reinstalling the game.
