dds exporting, its 64x64, why does it appear as 128x64???

[deadeyes1689]

for the rocket leauncher contrail i wish to edit it in painshop, i extract the DDS and open it in photoshop, it says its 128x64, when in HMT its 64x64?????? I think thats the issue, i follow the sticky above this topic for saving as a 32-ARGB and what notr after modifying it, but when injected it says the size is different and it has to be made smaller or something.... which is why the fact that is exports HMT as 128x64 is a problem.
