disable crashing flow on merge

[super gnu]

i clicked something during my random fiddling ( if i remeber well it was the "spawn on particle surface" checkbox..  which caused max to crash.. it saved a copy of the file first. 

however obviously, i cant open it...  when i do it just crashes again. 


is there a way to globally disable all flows before i merge it into a new file so i can untick that box?
