I got the game yesterday and it worked fine, but today I tried to (unsuccessfully) put a skin on my deagle, and now I can't get the game to run. I start it via Steam and it goes to a black screen with an error box saying:
"Could not find background image. materials/console/background01_widescreen.vtf"
I don't think I messed with anything but the folders and .vpk file I was told to in the tutorial on how to install skins, but anything could have happened. Any help is appreciated.
