Hello again Ozzman1O1,
May I request information about your Operating System? Windows Vista's user account control (UAC) is extremely awkward when it comes to editing files in the "Program Files" directory.

First thing you have to try, regardless of your Operating System, is editing the file again using these instructions. If that fails, and you are using Vista, simply follow the following instructions:

If you do have Vista, then first open up your "Computer" icon on your desktop.

As before, type "Control Panel" in the navigation bar.

The next steps depend upon whether you have the classic view, or the modern view enabled.

Should you be utilising the classic view, simply select "User Accounts" from the menu.

Should you be using the modern view, select "User Accounts and Family Safety". From there, click on "User Accounts".

Once you are into the area, select "Turn User Account Control On or Off".

You will then be asked for permission to continue. Either enter the correct administrator password, or simply click continue to move onwards.

From there, it is nice and easy. Quite simply de-check the check-box on the screen, and click "Ok".

After that, restart your computer, and use these instructions to attempt to modify the file again.

If you don't have Windows Vista, and you are following the said instructions precisely, then there may be a problem elsewhere. If you are entirely sure that you are doing everything correctly, you may have to ask the owner of the computer if there are any restrictions which could be preventing you from making the change.

Hope this helps, good luck, cheers!
