I am trying to download Lotro b on my new Mac air via Crossover Games but its not working. Please help.?

I went to this website http://www.mcgillsociety.org/PyLotRO/index.html and followed all the directions starting where it says Step-by-step instructions. However when i got to the part of quitting CXG and reopening it an then going to tools, settings wizard, LOTRO and then find games, nothing came up. PLEASE help. Thank you.
