Having problems taking metas from maps with HMT 3.5

[grunt934]

ok example: im trying to make my assault rifle shoot wraith mortars in the 1st map (poa)

I load b40.map (aotcr)
I go into Projectile > vehicles\wraith\wraith mortar
Click the Save Meta button (uncheck recursive)
I open a10.map
Goto Projectile > weapons\assault rifle\bullet
Click the Inject Meta button
Select "wraith mortar.proj.meta" and press ok
Click the Save button

now I load the 1st level and when I get the assault rifle and shoot it, my game crashes and boots to the desktop with a error saying "Gathering exception data".. what am i doing wrong?
