Hey, I've just got Minecraft and Forge yesterday and I've got a problem. I wanted to play some older mods and thought it wouldn't work, so I asked a friend for advice and she told me to change the Forge version (I have Java). I did and tried to play. The mods didn't work though. So I tried to change it back to the current version. But it didn't work anymore at all. While yes, I still got into Minecraft Forge, it didn't even show me a ''Mods'' button. I tried to reinstall it, but it still didn't work. What should I do?
