Why Can't I Open pickup_lights_d.dds in GIMP or any other software?

It just doesn't work. I want to create some new taillights with the existing ones as a base.
If I open it in GIMP, it says invalid compression format, and Blender can't read it either.
And while we're here, how do I make certain parts of the light light up with the correct function?

 

You have to use Paint.net to view .dds files. They can be exported to .png, edited in the image editor of your choice, and then converted back to .dds in paint.net.

 

I'm able to open certain DDS files in GIMP, now that they've added partial support. GIMP seems to not like certain DDS files from the game. What compression format do they actually use?

And upon opening the troubling file in paint.net, the same problem happens.

Code:

System.FormatException: File is not a supported DDS format

Thanks for the info, but I don't have Photoshop.

Also, it seems having the latest version of Paint.NET allowed me to open it. Weird.
