Why doesn't ReSharper work on Visual Studio 2013 Professional?

Question

C++ / C#

Downloaded the trial version of ReSharper on Visual Studio 2013 Professional. It is installed, sometimes it responds (when the development environment starts). But for some reason it doesn't work at all. Now more specifically.
On startup:

Press F2 (rename variable), confirm ReSharper.

I press F2 again to rename something, but in the end nothing happens.
Farther.
There are no auto-declarations of class methods at all, no type checking when casting types, etc.
Basically, ReSharper doesn't seem to exist in VS at all. Who faced this?

Answer 1

The solution is very simple: (ReSharper glitches with 2013 studio)
1. Remove ReSharper
2. Reboot the system 3. Delete the
folder [root drive]:\Users\[user name]\AppData\Local\JetBrains\
4.Download the latest build from the site ReSharper 5.
Install ReSharper
6. (if it didn't help) run the ReSharper installer again and press REPAIR
ps If even that didn't help turn it off in the Visual Studio settings and turn it on after restarting the studio.
