I recently installed forge installer and forge universal so I could get the mod. When I extract the files, as it says on http://coros.us/mods/weather2, and put it into the.Minecraft folder, nothing changes on my game and it doesn't say that any mods (apart from the default 3) are active or installed. I've never used mods before so could you please do step by step instructions on how I can make this work. I'm using windows 8.
This is the mod website: http://coros.us/mods/weather2
Please help as I can't find any youtube video that helps me with this particular mod.
