UO Second Age

when i create my char and try to enter world it just stays on the grey screen and says entering britannia? any advice? i can hear the music and everything its like im in the game but all i have is the grey screen

hi i think im being a massive noob here when i load it up what username and password do i enter? do i have to reactivate an old one, if so will i pay? how do i get a free username and password. sorry for asking whats probably a stupid question, havent played UO since BR
