Sooo...
I did a little searching and I found out how to fix this.
1st. Locate your Guild Wars shortcut.
2nd. Right click, and click on "Properties"
You will see a menu pop up that looks like this:

In the "Target" box, scroll to the very end until you see [-mce] without the brackets. Now just delete that until only the directory of your guild wars is in there. Do not delete that!
Now just click OK and your done! If you want to check out what else you can do with those endings just put a space after your directory and add one of these command line arguments: http://wiki.guildwars.com/wiki/Command_line_arguments
I haven't seen a guide out there on how to do this so good luck!
