Cannot open Mac App Store

Question

Using my Macbook Air running Yosemite 10.10.1, i downloaded the 10.10.2 update.  I shut the system down last night due to a low battery.  In the course of the shutdown it asked me if I wanted to install the update, I chose not to install 10.10.2 due to the low battery.  I restarted my Air today.  I tried to open App store so I  could install the update but the App store hangs and stops responding and I have to force quit App Store.  I have rebooted the system multiple times, both hard and soft reboot, and cannot get App Store to open.  Does anyone have any hints?

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
Click the Clear Display icon in the toolbar. Then take an action that isn't working the way you expect. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
