how do i get crossover to play games like lord of the rings online and medieval 2 total war?

[shinderhizzle84]

yea...the topic title pretty much describes my question: I am practically obsessed with lord of the rings online. I downloaded the installation files and it went fine using crossover, but then i tried to install it via crossover and it claimed i needed a valid version of windows. Anybody who could help me out with that? I am really interested in getting it to work, seeing as ive been playing so much of Wow that i literally see people as horde characters when i walk down the streets . Haha, no, not that much, but im getting pretty bored of it. If ANYBODY at all could give me a detailed, step by step guide on how i can install a game on my intel based macbook using crossover, thatd be awesome. Thanks again!
