Browsers/Mail :: Icon On Start Screen Doesn't Open Email - Windows 8

Likes to use the Windows 8 Start Screen that has all the tiles on it. Normally, she clicks on the "Mail" icon to get to her email, but now when she clicks on the icon it doesn't go to her email and instead it goes straight to her desktop. I tried clicking another icon; the "weather" one, and it too goes to the desktop. She told me she downloaded a couple games from iWin a few days ago and I noticed a new toolbar in her browser so I tried disabling that, but no change. I've checked what the default browser is, Internet Explorer (what she normally uses). I also tried making Chrome the default browser but still no change.
