Invalid File ID?

  • Intel Quad Core 2.66GHz
  • 6GB
  • Geforce 9500
  • Windows Vista 64-bit

Fresh install no mods or addons

When running Garry’s mod the game will come up to the loading screen, get 75%ish of the way done loading then crash with a Invalid File ID for garrysmod f\resource\closecaption_english.dat

Ive tired reinstalling the game. I have CSS and HL2 for my sources. The above file also dose not exist.

Any help? I’ve searched these forums and the web for a few hours and can’t find anything.
