World's first frame accurate H.264 AVCHD cutter without re-encoding!

I have been using this software for some months, but today when I’ve tried to use, it won’t play any videos at all – nothing else has changed with my system or how I’ve edited videos successfully in the past. Everything else (scrub forward/back, frame by frame etc.) works fine. I have version : 1.9....

I have exactly the same problem; "use source folder" is unchecked, but file is not saved to the path I've input.
