User Authentication Failed (Before enter launcher)

[DJNdeath]

My problem is similar than the post before. I got banned other times, IP ban, MAC ban, etc etc. I solved it with Tmac, Volumeid, and other. When got banned, it says "User authentication failed" when i pressed "play" now, this error appears when i go to join launcher. With any account, new accounts created on other PC's, same error, i can't join launcher. I got lan card ban? Help me please

Did you try to clear cookies in Internet Explorer? Those accounts that you are trying, are they working in other machines?

I didn't create any account with PC because i thought that obviusly won't work anymore, so.. No, i didn't do that, all the accounts that i create was in phone withouth Wifi. PD: A friend from Mexico create one for me on his PC and i got the same error when i try to join launcher with the account.
