Uberminecraft Help!

So I just got a V.I.P in Uberminecraft. There was a guy giving out V.I.P in The Walls with my friend. This was the command (I think): /accept (password) (email) I started the using the V.I.P in Super Craft Brawls but I started using the V.I.P in the other Server Games like BombCraft but can't use it.It says that I have to purchase the V.I.P over their website. Help me those guys who plays Uberminecraft with V.I.P?

Server I.P: Uberminecraft.com
