I made a mistake while copying 1.2.5, no big deal. I knew that I just had to wait for CraftBukkit 1.3. When Jigs finished getting the server ready, I went on to play. But when I got on, there was so much lag it wans't any fun. Later, I got the annoucement about the server not staying on 1.3, and going back to 1.2.5. That is fine if I could just figure out how to download Minecraft Version Changer. Could someone please give me stepes about how to do that?
Download Minecraft Version Changer here. Once you download it, double click it to launch it. From the drop down menu choose "Minecraft 1.2.5". Click "Change" Test Note: You must have minecraft already installed on your computer in order for this to work.
