Having problems getting FIFA 07 to 1680 x 1050.

Hello. I recently got FIFA 07, and I've been searching this forum and everywhere else for solutions to get the game into widescreen. Well, I came across a couple here that involve using the hex editor, but I can't seem to find the string that I need to replace. Here's the link to the guide that I'm going by: [url]http://www.widescreengamingforum.com/node/7780]
I've gone into the game and made sure the resolution is set to 800x600, and I still can't find that resolution string in the fifa07.exe. I'm not sure what else to try, so I figured I would see if any of you had any suggestions or anything to help me out. Thanks in advance for any help.
