Sometimes that can happen with large video downlds. I don't know why but it seems to stall. You could cancel it & re-select from the search results to see if that helps or re-search the topic. Otherwise, go to the LW Library window, select incomplete folder, then select that video file & press the Launch button. Then scroll to the end of the video to see if it's all there. If yes, then cancel it from the download window, go back to Library window & incomplete folder & press the Explore button. This will open the folder for you. Then you can move it to where you'd prefer.
