That is the message you get if the file is named Info.txt.plist, so make sure that "hide extension" is off when renaming so you can make sure it's "Info.plist".
Nope, identical. Could you maybe send me a zipped file of everything complete, I've followed the instructions several times trying different things and don't know what the issue could be?
pretty sure info.plist is being saved as RTF (rich text format) as you can see in the icon of the file in the screenshot you posted. in TextEdit, you can do Shift + Cmd + T to switch between plain text (.txt) and rich text (.rtf)
