Yeah I don't see the Global Faction line, I noticed you change the pathing of the script to units\ instead of scripts\ like it is in the OP, but your factions is still in scripts\ if you left everything the way it is it should read:
_aispawn = [[4482.47,10287.6,0],1,1,8,0,1,3,6,0,200] execVM "scripts\add_unit_server.sqf"
and not
_aispawn = [[4482.47,10287.6,0],1,1,8,0,1,3,6,0,200] execVM "UNITS\add_unit_server.sqf"
_aispawn = [[4482.47,10287.6,0],1,1,8,0,1,3,6,0,200] execVM "scripts\add_unit_server.sqf"
and not
_aispawn = [[4482.47,10287.6,0],1,1,8,0,1,3,6,0,200] execVM "UNITS\add_unit_server.sqf"
