I recently changed my name, to make sure my name would be available. I tried to log onto smp9 today, and the screen said "Not Authenticated With Minecraft.Net" I have no idea how to fix this, because I have to wait 30 days to change my name. I also should be able to log on, and use my old name. When typing in my single player world, my old name is still there even though I changed it. Anyone know what is happening and how I can fix it?
