Hello, everyone. I'm on Vista, and have installed Leawo Free YouTube Downloader; the program is here - http://www.leawo.com/youtube-download/. This program worked fine in the past two weeks, I have used it to download some online videos to my computer. But now, the youtube downloader does not open. It appears in task manager as a process but not as an application. The process is still taking up 50% of the CPU. Any way to make the window appear?
