skid, that's a pretty general statement. You need to tell us more. What do you mean new source mod folder? If your plugins are not working then it sounds like SM is not loading or it's possible your install is not correct. What version are you using Linux or Windows, did you install the correct version? There's a lot of troubleshooting many of us can help with but you need to really give us a lot of info to help us try and help you pinpoint your problem? Are you a new SM user?
