For some reason trailers won't work for me anymore.

They used to, but they just stopped working.
They won't load when I highlight the movie - press "i" "trailer"

Sometimes I'll get this message -
"Playback failed" "Couldn't locate video URL"

Other times I won't get any message at all.

Any ideas?

Well, they are found through youtube I think. If the addon can't find what it deems to be a match, say on a strange old movie, then there won't be a trailer. As for no message at all, I'd say there is something wrong(missing script maybe).

Your best bet would be to post a full debug log of events on the forums and see if someone can figure it out. I'm not exactly an expert
