SeTTo

So, I purchased a copy of GTA:SA from gamestop a few months ago. Played it just fine. Found MTA and played that for a while as well. Deleted SA and MTA from my PC one day. Recently got into it again and re-downloaded my SA from the gamestop impulse reactor app just as I did before Installed MTA, but when I run MTA it just runs SA and brings me to the load or continue menu, and not to the MTA menu. Whats going on here? thank youu -Mark
