First off I should let you know that when it comes to computer I know just enough to be dangerous. I was having some issues with my outlook.com and after clicking and unclicking I pretty much got lost. I did a refresh because it sounded clean. When I logged back in it showed the apps that I would have to reinstall but the office 365 was black. There was no link. I tried to reinstall it using my product key but it won't work.
Software/Hardware used: I have a Toshiba Satellite laptop L55-B5294
