On Theages guide, I need some help, since somethings really confused me.

I've done step 1 through to step 11 (I left out 12 since I didn't see the point in having night battles either) but step 9 really just doesn't want to work.

I assume that the shortcut that needs to be edited is EB 1.1 Singleplayer, but every time I try and edit the 'Start in' box I always get the same pop up box when I press enter. The box says

The folder '"C:\Program Files\ EB 1.1 Mod\RomeTW-BI.exe" -mod:eb -show_err' specified in the Start In box is not valid. Make sure that the folder exists and the path is correct

The problem is the path is correct and the folder does exist. Any suggestions? Cheers
