Very few mods work with the trial version. I doubt that this is one of them.
It's probably because the trial version only has one system included, which is New York, so it creates jump holes to new systems, but since the trial version only supports New York, you never get out of the jump because there simply isn't any system on the other side for you to pop out of. I've never used the mod, but that does sound like the problem you are experiencing.
My recommendation would just be to buy Freelancer. It's really not very expensive, being over a year old, and it sure is worth it, especially if you use mods after beating the storyline. Simply put, the only trial-supported mods I am aware of are the few that come with FLMM. No mods that add systems or anything will work with the trial.
