Alright. Got my CD finally (I lost the web installer) and, after installing it on boot camp (successful) I brought it over to the Mac side.
Crossover caught the CD, and using an express install, I got the installer to load. After choosing standard install, It closes and goes to bring up the actual installer program, which promptly states "Hellgate: London Setup Wizard ended prematurely because of an error."
Also, for some reason HG:L is not in my advocated programs... but I'm still on the main page :/
