Spotify won't let me log in?

[♥Elise♥]

I'm trying to download spotify on my school computer in my programming shop, and i should be able to download it as long as i can log in. but i can't. i've previously logged in with Facebook but FB is blocked on this network so i try manually logging in with email but is says that the @ symbol is forbidden. then when i try without the @ it says it's wrong and to log in with my email. ??? anything i can do? I really want to listen to my playlist while working.
