I have Visual Studio 2012 + Resharper 7.1.1000.900 + StyleCop 4.7.44 installed.
The problem is that no shortcuts
I would first try resetting all Visual Studio settings (Tools > Import and Export Settings > Reset all settings), then go to the Resharper > Options > Keyboard & Menus and re-apply the keyboard shortcut scheme.
I had to do something similar once.
