I'm using Photoshop CS (old, I know) with Nem's VTF plugin. None of the VTFs I can find will load, save a few that were apparently reused from other games (CSS, etc). The VPKs were extracted with [this tool.](http://blog.gib.me/2009/07/07/left4dead-vpk-extraction-tools-updated) VTFEdit won't start for some reason, so that's not an option. Also, I'm looking for the Earth texture used in the ending.
