Texture doesn't tile in game

I'm using gameSpace/Dark Industries DTS exporter to make a crate, simple enough it seems. Modelling fine, uvmapping in gS no problem, but when I get into the show tool, the texure doesn't tile. It's clear from the shot I took and the texture used that it goes dark and blurred at the edges of the bipmap.

(The following link probably won't work unless you right click --> copy shortcut, then paste that into the address bar, no idea why, thanks Rex)

Any help on this would be much appreciated, I'm pretty sure it's nothing to do with the model as there's no edges near where it goes wrong, and I have remodelled it again and the same thing happened.

Thanks alot,

Ray

(p.s I've only uvmapped the obvious faces here, just to prove the point, don't worry about the others)
