Can't open AppStore and Email app after installing the OSX Update 10.8.3

Question

Hi there, after I installed the OSX 10.8.3 update I can't open my Email and App Store apps. This is the popup message that appears when i try to open those apps. I tried to reinstall the app but I can't open my App Store. I also downloaded and installed the OSX Update 10.8.3 and the 10.8.2 again from the download support page, but I couldn't solve my problem. Does anyone knows how can i fix it?

Back up all data.
Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
When the OS X Utilities screen appears, follow the prompts to reinstall the OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
