[INFO] Help

Guys, Sorry for not making anymore missions, its just that i downloaded arma 2 operation arrowhead, then installed the directx9 along with it, after that, i couldn't start SA anymore, when i double click SA it just shows the loading mouse icon then disappear seconds later, tried deleting the gta_sa.set in My Documents, Nothing happened, does this mean the directx9 from arma2 OA ruined my SA? any answers would me much appreciated^^
