First off, thank you for responding, I really appreciate the assistance.
Yeah I saw that video, the guy is talking about enabling widescreen on a steam version and I have the original retail copy of the game (I probably should have specified that, sorry), and it's patched to 1.0b.
I was afraid to follow the instructions in the video because I didn't know if the steam method and the retail method were compatible, and I really, really didn't want to screw it up and have to uninstall and reinstall everything, starting all over from scratch. However, that being said I just decided to go for it and see what happens and everything seems to be working alright.
Thanks for your assistance!
