Answer 1

I suggest reinstalling IDEA. Perhaps download the installer from their website first from http://www.jetbrains.com/idea/download/index.html

The issue is most likely cause by the update screwing up the rights of some of the files. It is probably possible to fix this, but a reinstall is easier and faster so just do that.
