Thank you for posting! It sounds like Internet Explorer is still open in the background. I would recommend going into the Process tab in the Task Manager to check to see if it is still open.
This article will further explain how to do this.
If you have any other problems, feel free to respond or call in at 1-877-467-5464. We are open seven days a week, 10:00am to 10:00pm EST.
Hope this helps!
