Maxal did you find a solution? I am having the same problem. Game was working fine, but then my graphics card died. I got an old replacement card from a friend GTX 260 which seems to be working great and every other game is working, but when I try and play lotro the same thing that happened to you happens to me. The launcher loads fine. When I select a world and hit play the launcher closes, but the game does not load.
UPDATE: After digging more I finally found the suggestion from other threads about deleting the userpreferences.ini file in the documents folder. That fixed my issue
