[A Higuy!!!]

I was at tojehusiza's server,and he had to close down. so i let my friend Xzero play on my account for a bit,he changed his name and clothes,And he joined a server,crashed,and ever since then my blockland opens,It authenticates,and as soon as the name appears and starts flashing blockland just closes.
