Hello and welcome to BBB! I'd suggest going to Tools/Internet Options from your browser window or go to Start/Control Panel/Internet Options. Go to the Security Tab and (assuming you haven't made a lot of changes) just Reset all Zones to Default Level.
If that doesn't work you can choose Custom Level and check your scripting settings against the computer that does work properly with WLM.
