I tried also to use mortar with no trainer activated; useless to say, nothing.
Someone else got this problem (and solved it)?

In main of "Call of Duty- Modern Warfare 3\players2" inside the folder players2 : delete all folder not file keep the regular file only folder delete it except (autosave)
and any file inside players2 & autosave name it hijack file somthing like that delete this file
run the game without trainer you see can't play resume but can play "Mission select" inside the mission select (ACI) and Back on the Grid
when you play be careful when say partner stay do as he want . when you reach the Mortar you see In screen Prees and Hold "L"
