YoVille will NEVER ask for your password, so please be wary of malicious emails and/or forum posts that request your password, including via web links.
Sorry to read that rose, if you haven't already try accessing the game thru a different browser than the one you are using and check if that makes a difference.
If it doesn't please submit a ticket using the help button above the game screen and the Player Support Team will take a look and see what is happening on your account.
