Sorry to hear about the texture problem
(my standard Lenovo T500 laptop isn't the best and only medium settings available but i never see the brown troop problem) and it doesn't work when lowering unit details or any of the GPU demanding settings?
Fortunately LME1.5 is still available on Megaupload here:

I will not delete it until ReignTerror has posted here submod.
I will check that mip-maps are included in the dds files from L'aigle (they are for all other LME graphics) and if not I will make sure they are in LME1.7.
Best regards
