Hello, everyone!

I have played lotro like 3 years ago... on july 2013 I had login again just to take a look on my characters, being afraid that they could disappear due to my inactivity. They were there! But today they are not anymore! Sadly, I don't remember which world I was playing, so I tried to login in every world available, but didn't find them =(

I had a Captain, a Rune-keeper and a Champion (47)... what should I do???
