问题
My Visual Studio 2013 had started to not let me make new projects (or see already made ones) on my computer.
I have installed it again 2 times, but alas, it did not work. All it did was take up 3 more gigs of space each time.

EDIT: I cannot click on the exclamation mark on the top left. Just a blank box when i hover over it.
FIX:
I completely uninstalled it, and reinstalled it by downloading it again from Microsoft. It works Now, as i now can click "ok" and make a new project.

I Reinstalled Visual Studio 2013, from scratch. By Uninstalling it (not repairing it) and installing it again, it works now!
