If the OS Downloader, Help, and Options buttons don't work, there was a problem
on installation with permissions that blocked the creation of the ini file used by the program.

I have placed a link below for you to use to download this file. Right click the link and select "Save Link As" and then
save to your desktop.

Please place the file in the following location

In the Finder, choose Go > Go To Folder.
In the Go To Folder dialog, type ~/Library
Click Go.

Once the Library folder opens go to
Applications Support >> Download Surgeon 2

In this Download Surgeon 2 folder, please paste the "sniffer.ini" file that you downloaded.
Once you have done that open the program again and try the Help and Options Buttons.

You will need to open the Options button and reset the paths to locations on your machine.
