Account Banned or Password changed ?

Hello Nostalrius GM's,
Recently (about 3 days ago) I noticed that I couldn't log in to my account and it always says "unable to connect", so I guess it's either banned or someone somehow changed the password because he has access to the account ?
So First I'd like to know if it's banned and what the reason would be (or simply check if it was a mistake?
) and second, I'd like to know if the password has been changed by someone and how I could revert it ?
Account Name below, not sure if it has to be censored
Thanks in advance,
Grip
