I'll attach it if that doesn't work. Also, it seems that it was just files I opened on that day, not necessarily files that I saved on that day, which is strange.
[edit]
I've compared it to another file, and here are the places where it differs from the uncuorrupted file:
}
texture { "[texture]"
  file { "C:\\Program Files\\anim8or\\[texture].jpg" }
}
object { "object01"
  material { "material01"
    surface {
      /* RGB chunk no longer used */
      rgb { 224 224 224 }
      lockambiantdiffuse { }
      ambiant {
        rgb { 224 224 224 }
        factor { 0.30000 }
      }
      diffuse {
        rgb { 224 224 224 }
        factor { 0.70000 }
      }
      specular {
        rgb { 255 255 255 }
        factor { 0.20000 }
      }
      phongsize { 0 }
    }
  }
The other file didn't have a tecture, so I couldn't really compare.
Also, the data here seemed to be in a different format on the corrupted file:
}
    faces {
      4 5 0 -1 ( (0 0) (1 1) (9 2) (8 3) )
      4 5 0 -1 ( (1 1) (2 4) (10 5) (9 2) )
      4 5 0 -1 ( (2 4) (3 6) (11 7) (10 5) )
      4 5 0 -1 ( (3 6) (4 

 (12 9) (11 7) )
[and so on]
is there anything odd about this?
