Deus Ex Alpha

As I have become increasingly bone-idle, I gave up looking for my Deus Ex install CD and now have the Steam version to compensate. However, I have recently noticed that it seems to have issues loading many of the CoreTex... texture packages, along with quite a few other notable ones. This is proving to be quite a pain to work around, since I need quite a few of the WallObj and Textiles packages (among other things) to work on my Resident Evil maps.

Does anyone know of a workaround using the Steam version, or am I best off getting the .utx's off my old disc (provided I can find it)?

Well.. here's all the textures if you need em'

Just have to put those two in the 'Textures' folder and then extract from the executable.
