So, I have the Mod downloaded, have the FPS installed.. but my problem is this: I don'tknow how to play the mod. I have it selected in my mods, but how do I start it? All of my icons are Resident Evil'd and the music as well...but anytime I start a campaign, it just starts me on one of the preset L4D campaings. What am I doing wrong. . .? Is there something I'm missing? How do I start/begin playing this amazing looking campaign?

PS) I am BRAND NEW to PC and Mods. I've always played consoles. So this is technically my first PC. .therefore a lot of this PC logic is over my head. I have successfully enabled other mods for L4D. such as character skins and other campaigns.. .Just not this one. Any ideas what I am doing wrong? Any assistance would be phenomenal! Thanks in advance!
