ReDem Terrain loading problem

Hey Everyone i hope someone could help me with a problem i'm having.
I've got my data from the usgs site and tried to load it with ReDem(payed version). The problem i'm having is that it has only loaded a handfull of terrain tiles that are only in the background of my route and they are just spread out randomly. I know my coordinates are ok as the marker path i've used is on the ground at the start position and it's the same one i used for ReDem. I have over 800 bin files for the terrain and have checked a good few of them with rwtools and they seem to be complete.
i've also checked the original bil file in microdem and it shows up fine.
Out of shear frustration i even tried converting the bil to hgt to load it that way but it didn't work either.
Any help would be much appriciated.
Thanks
Roy
