I uninstalled the original LOTRO client that isn't from Steam. I then installed the game from Steam. The game works fine! However, the only thing I've noticed that is different is that the desktop icon is no longer a ring. It's just a boring piece of paper! I'm guessing that this is normal, but I'd like to hear from others who downloaded LOTRO through Steam as well.
Yes thank you for this, I remembering doing something like this a while ago but just forgot how to do it! Good thing google picked up this post, dunno why steam hasn't done this yet considering they display lotro on the front page of the f2p genres...
