Okay, so I just installed the best game ever on my computer (better known as Minecraft). I am completely new to Ubuntu, but I got it to work after a bit. It came as a .jar file, so I had to download this Sun Java 6 Runtime stuff to open it with, and it worked great. For those of you who play Minecraft, you should know it is in Beta testing and there are many different versions. I wish to play 1.4, and it is currently at 1.5. I went to my .minecraft folder where all my minecraft stuff is located, and I replaced the bin folder there with an older 1.4 version I had saved online on my windows computer. I closed it, tried starting minecraft, it popped up, I logged it, I clicked "do no update", and it gave me a black screen. Sorry if I have not provided enough information. Can anyone help me on this?
