Ahh, have you changed your username or password recently love? c: That could be the culprit, it's been happening, a .//lot due to forum changes and updates, please bare with it all until it's fixed! But that's the first thing.
The second thing is, if that is the case, please send a password change email to Raz I believe and you can change it there.
I suggest trying to switch browsers, though. It worked for me!
Hope I helped.<3
