I've had this happen a few times. Take a look in your Incomplete folder and your Downloads folder. If you find the file in the latter - no problem. It's already moved to where it needs to be and you can select the file name in the downloading list and delete it with the Cancel Download command. If the file is still in the Incomplete folder, you can drag it to the Downloads folder and THEN delete it from the Downloading list. However, this will only work if the file has actually been downloaded - check the file size.
