Screen Capture with Transparent Windows and Mouse Cursor

Hi!
First of all thanks to Sean for this awesome lib!
I been using it for a while now, but lately, as I moved to Win8.1 64bit, part of it that converts captured image to file stopped working. I.e. I can still capture part of screen and it will be on clipboard, but it doesn't save it to file the way it used to.
I've searched for answers on this & other forums, but couldn't find anything. Could anyone please help me, what needs to be changed in the code?
Btw, I tried running script as Admin, and opening it with AutoHotkeyU64.exe - it didnt help...
