I've been playing Minecraft for years now, however I ran into a problem I haven't before: when I opened Minecraft I only had version 1.16.2 and a couple of modded versions. I remember adding some vanilla versions but I just assumed it was nothing.
I went to installation to get a new 1.8.9 (I wanted to test some old worlds), went to versions and there was only version 1.16.2 and a couple of modded versions. I went to make sure that snapshot and historical boxes were checked and they were, I closed the browser down and opened it again still happened.
I went in the .minecraft folder, saved all the important stuff, uninstalled the game and installed it again but now I can only go on Minecraft 1.16.2.
To fix this I cant get the other versions simply cause it wont let me.
