My sister and I recently upgraded to Windows 8, and yesterday we were playing Minecraft like normal. Then all of a sudden we got this pop-up for Java. I clicked on the popup, then I got kicked out of the LAN and she couldn't join mine so we restored our computers back to when Minecraft would let us play together.
So we uninstalled java, and re-installed Java 6. It worked for her and when I went to open a single-player map and it froze. I tried opening Magic-launcher, and it would load the map but I would constantly lag then finally crash.
- When I say restored I mean I backed up to an earlier date.
- I have no mods installed
The popup asked if I wanted to do something like share my java with public. When she opened her LAN when we got them working I clicked no because when I clicked accept it wouldn't let me join her LAN
