Looked all over, but couldn't find the answer

I'm having trouble logging on to world servers. Everytime I go to login to the game, a message pops up saying, "Although you've registered Shadows of Luclin we cannot find the folder containing the files......." at the bottom of that message it says that it may cause the game to not function. Anyways, after I click continue it starts to load up and I get booted back to the world server menu. I don't have Shadows of Luclin installed and I never registered a copy. Is there anyway I can fix this, or will I have to go out and by SoL?
