i changed "screen shot enable" to 1 in the ini but when i try to take a screenshot it still gives me the message saying i need to change the ini

What OS are you using? I might know the problem...

Do you use MGE? You need to fiddle with some settings there too.

This is the problem I had last time; if this is the issue here:

All you need to do is go to MGEgui's input tab, launch the macro editor, and set a key Function to Screenshot. You can also choose what to save it as (jpg, bmp) in the Global Graphics tab.
