[ART] [SOLVED] Custom decal malfunctioning

[Slanderous]

I've been trying to re-color one of Amnesia's vanilla decal textures, that is "blood_pool01". I used paint.net, and while I was able to export the texture directly into .dds format with A8B8G8R8 settings (checked the settings for the vanilla texture, were the same as mine) the texture is displayed unproperly in level editor -- it's shown in spoiler below.

Spoiler below!

(left is how i want the texture to look like, right is the screwed up one)

Any ideas to fix this tiny annoying tidbit?
