Graphic problem with cannons...

[MacIronhawk]

For a while now, anytime I use the cannon all my Firebrand amo shots appear to be black instead of flaming like they should.
Is there a graphic option I might have turned off for that or...

EDIT: Also, here's a picture of what happens when my ship battles a ship that has a graphic issue.


First my amo turned black and now my ship.(but it only happens to things where flames would be.)

On the other hand if this can't be fixed I get to have a nice, scary looking ship like I've wanted from day one.
