A total noob here unable to install the demo auto-recorder plugin. I copied the "addons" folder to my "steamapps\common\Portal\portal" folder and tried renaming both the "speedrun_demorecord.dll.4104" file and the "speedrun_demorecord.dll.5135" file to "speedrun_demorecord.dll", however when I load the game I get a message "Failed to load plugin "addons/speedrun_demorecord"" either way. Anyone have any idea what am I missing/doing wrong here?
