Fatal error W_LoadWadFile: couldn't load gfx.wad

[MrDemonic]

Everytime I try and start this up, it crashes on start up with the error message in the title. I have tried verfying the game files, reinstalling the game, reinstalling Half-Life and then Opposing Force and, even restarting my computer.

I am not sure why this is happening as I managed to play this perfectly fine a few months ago. But after trying to boot it up for the first time in a while seems to have caused this.

Any help with this?

Same here, nothing works.

This is some error caused by Steam, the official install directions were changed, I fixed it for CS and HL by deleting everything and all folders of HL and CS under Steam\Steamapps\yourAccName (delete absolutely everything), then you should do one clean installation and Steam will install the games in the proper direction, in the common folder. Now it will work just fine.

Have fun

How you do that? one clean installation and Steam will install the games in the proper direction, in the common folder?

I recently advised the following from the technical support:
"Please try the following:

Exit Steam entirely.

Browse to your Steam installation (Usually C:\Program Files(x86)\Steam\)

Rename the "steamapps" folder to "old_steamapps"

Re-launch Steam and re-install the game.

Once the installation is complete, test the issue.

If this resolves the issue, you may copy the new files into the "old_steamapps" folder and rename it to "steamapps" to restore your other games without re-downloading.

If the issue is not resolved, you can rename the folder back to avoid having to re-install other games."

I did everything as it is written, and it worked flawlessly, and as if there were no problems

I had this problem with some Valve games and after trying everything else (exept reinstalling Steam) i found a solution:

INSTALLING THE GAME/S IN THE PC INTERNAL HARD DISK

Apparently, majority of Valve games (especially the older ones) didn't like to be installed in an external HDD.

It is quite annoying for me that i play on a laptop but in my case that's the only think that worked.
