Hello, I have been having this problem for a while now, that is that the file explorer option that appears after right clicking the start button on the windows 8.1 does not open the file explorer. I have been using the pinned file explorer option on the taskbar to open and somehow continue working. Click image for larger version

And today I saw that right clicking on the firefox tab to open a new firefox window or tab does not work either.

But right clicking the explorer tabs to open a new window for file explorer works. I cant seem to find out whats wrong and I dont wanna reinstall my OS, which is really gonna be hard with all the data I have saved in.
