I an old email from when I attended minecno back in 2013 I had 2 but I used one on my account but now when i try to use it it gives me an error any help?
its probably just too late to redeem it now seeing its over 5 years old, but you would have to ask Mojang that as only they will really know
well wich one did you try the one that you used on your account or the one which isn's used?
Unfortunately I can’t provide any suggestions on what to do but I agree with the post above the one on mine, it’s probably old. ;-;
