Are you using an ability that uses ApplyBuffTo[Something]WithTravel? You shouldn't use beam particle effects with such a structure. Rather you should use ApplyBuffToTarget combined with a cosmetic "PlayPersistientBeamEffect". Look at something like Cleansing Brilliance for an example.

ApplyBuffToTargetWithTravelNoFilterNoRange is usually used only in buff files called by ability files that use "ApplyTargetedBuffToSelf", not in ability files directly. That could be the cause of your error, and even if it isn't you probably don't want that, as it is you'd basically be able to cast that ability on anything, friend or foe, planets, stars, ships, fighters, mines etc. You should probably use ApplyBuffToTargetWithTravel if you want to make an ability work like a projectile weapon, so you can tell it what sort of targets to hit and give it a maximum range.

pastebin your files. It would be easier to provide specific help.

I actually figured out my problem.  Thanks Goa.  My main problem is that I was trying to model my ability off an ability that didn't really match what I wanted.  But still, that still helped a lot.  Thanks again
