There are some things that could be the reason for unsuccessful logins.
It could be a misspelled email address. Sometimes a comma (,) is inserted instead of a period (.).
It could be that the ending of the email service is wrong, for example you could have replaced "hotmail.se" with "hotmail.com".
Sometimes there is a connection to Facebook, and you are trying to log in with your email address and password. In that case try to login using Facebook instead. We have also noticed that the Facebook account uses an old email address and you may have switched recently, that could also be a reason for failed login, or attempt to reset a password, when the reset information is sent to your old email address because that is the one we have registered in our system.
If you still can't log in, submit a request, and we will help you get access to your account as soon as possible.
