Compressed texture modification

[3DModelerMan]

I'm working on a compressed texture patch. It's my first time trying to make a change to the engine, so I'm still trying to find my way around in their. I'm trying to get it to work when generating mip-maps, but it crashes somewhere in Copy32BitMipMap. Here's the patch file: http://www.mediafire.com/?wzu3ocwv8mst628
Would someone mind taking a look and telling me what I'm doing wrong?

There are problems related to the texture size. Have you tried to do a step by step debugging inside that function to find out where exactly it crashes? Be carefull with aotomatic mipmap generation in compressed textures where there is extra padding when downsampling textures. Have you tried by manually setting up custom mipmap levels?
