error code3:

[user-removed]

After using spotify last night as usual,somehow spotify logged me out. I am typing my password and can login for 2-3 seconds. And after that spotify logs me out with error code:3   when I type a random password in there,it gives error code3 right away (obviously),but I am sure I am typing the right thing because I can actually login for a few seconds before getting kicked out. 

Looked at forums. Tried typing just username (without the @gmail thingie),tried typing the username provided with premium (the long one with random numbers and letters), and tried logging in with facebook account (it logs into a free account,whereas my account was premium). Can't see a 'forgot password?' thing either. Can anyone help?
