I've just uploaded version 1.13. With version 1.13, you can open textures into Texture Studio from the command line, so now you can associate images with it, drag images over Texture Studio's icon, etc.
I really don't know what could be causing the memory access violation, since all my computers work fine with it. I really would like to get this fixed, so I included a possible fix for the problem in Ver. 1.13. If it does not work, I probably will release the source code of Texture Studio for anyone who would like to step through it and maybe see where the problem is, or even use the algorithims in their projects if they would like.
