Trouble to have my pic working.

[Sl4d3]

Hi,

As we said "we're never aswell served than by ourself", so i started making my ui today.
Using TGA and alpha channel, the picture is perfect. But with dds the size is much more low so i would like to use them instead.
I saw some post about DDS, (i use 8:8:8:8, and photoshop CS).

In the builde everything goes fine (except the image background wich ain't transparent.. but atleast the pic show right). As show in the image ->


But when i try in game the image's just a white square ->


I tried several setting and can't figure out how to fix that. Any help would be much appreciated, thank you !
