At a guess, you might be using the line tool rather the pen tool. So you'd want to make the line using the line tool, then switch to the pen tool to move it around (thats because if you try to move it with the line tool it move all the...erm nodes (I use the word nodes for everything it seems) but if you try to move something with the pen tool it'll only move the node you have selected)

Another thing it might be is that you are clicking and dragging to high up on line rather than at the tip of it

That's the best I can do at the moment I'm afraid, I'm away from photoshop for a week

I had a little look at that filter but I couldn't really get what I wanted from it. Wanna do a google hangout sometime and go through it? See what it's capable of
