Eh, they work for me. By the way, everyone payed for their trails. Anyways, is your computer graphically able to use motion trails? (Shouldn't be a problem if you can use shaders. Most people who even can't still see them.) Post your graphics card here, and give us a screenshot of the trails in your inventory. If you bought them in the last version of toribash, try deactivating then activating them. Nobody has had this problem before, so don't expect a quick solution.
