When you un-installed the game, did you make sure you deleted all the folders?
And have you logged in anything in the 1 year you've been gone? I'm not sure, but it could be possible that your in-game account could've been deleted because of un-activity.
And are you sure you had the same in-game name as you have here on the forums?
Check out \\The Big Help Thread// (http://www.feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&topic=10423.0) and see if you can find anything there that can help you, if not then I suggest contacting one of the admins or moderators.
Good luck~ // Shallow
