SAO Rainmeter skin

[Lynked]

So i installed the SAO rainmeter skin today and i wanted to change the standard web browser to Firefox. So i went and found my Firefox.exe location and pasted it into the SAO menu.txt, refreshed the skin and it doesn't work. Here is what the code looks like: HideMeterGroup mnItemn]["C:\Program Files\Firefox\firefox.exe"] If anyone see anything wrong with it or have any suggestions on how to fix i'll gladly listen to them.
