When logging in to Minecraft the other day I noticed I had to log in using my e-mail address so I tried and went to Mojang.com to transfer my premium account. After waiting nearly 5 hours for a simple verification e-mail it was verified. But, when logging in to the game (using the new launcher) I could only play the demo version. This was the same for the old launcher. I went to Minecraft.net and logged in (using e-mail address) it showed that I had not even purchased the game. (I know by looking where you change your skin it said "You have to purchase the game to change your skin." under the profile tab.
If anyone can help please post on this thread.
