Apologies if I didn't search well enough for an answer.
I am unable to take screenshots. Every time I attempt to do so, I get a "failed to convert to PNG" message, and nothing in my screenshot folder. No matter what I try to take them as- bmp, jpg, png- whether or not I get an error message, nothing in the folder.
Running in various compatibility modes hasn't helped. Nothing has helped. This is a fresh install of Windows 7 x64 Ultimate.
If this is something really simple I will feel really stupid.
