Can't Compile (File read failure)

My map had been compiling fine until I retextured a room. So here's the important part of my log:

Using mapfile wad configuration
Wadinclude list :
[zhlt.wad]
[vlv_ramassis.wad]

87 brushes (totalling 534 sides) discarded from clipping hulls

added 2 additional animating textures.
Error: File read failure

I've never received this error before and have no idea what is causing it.

Please help!
