Image in tga format showing up in UIBuilder but not in game ?

[Gistum]

Hello,

I've been playing around with UIBuilder lately but something is pretty weird.

Im trying to remake my old EQ1 player window.

In UIBuilder, everything looks great, all the images are at their place.Though when I load the game, only the gauge bars appear 0_0.
The images are all in the .tga format, dont know if the .dds one would fix that ?

I will attach the ss later if needed.
