Thank you Lord of the Rings for your immediate response and concern. Unfortunately, the solutions you have suggested doesn't work. I have tried searching all incomplete folders, but none of them have the incompleted file. I tried file locate on the stalled download on LW, but it is located on a folder without any files on it. Totally weird... I have tried also deleting the incomplete folder.

Every time I restart my computer or reinstall LW, the stalled downloads keeps coming back. I have to cancel it manually.

Anyways, I appreciate your help Lord of the Rings. If you can still think of other solutions, please do. I still want to solve this problem.
