The same thing has just happened to me
the same thing just happened to me!! I was inactive for a couple months and when I came back I could not get on. My password wasn't working and like you I went to the Forgot Password link. But, I never got an email for it. So, I went to forgot username and low and behold, my LOtRO account no longer appeared when the list of accounts linked to my email came through. I just put in a ticket, but I'm worried. All my personal info was on that account. What if they start stalking me or using my info?
