I was having the same force close errors.
I cleared cache, then uninstalled updates, and then installed version 4.4 again. It worked the first time, but then forced close the other times. I then cleared cache, removed app data, then restarted the phone. When it powered on, it automatically updated. The app then worked the first time, but not the second. I then cleared cache and app data, restarted, and then the app worked. So far, it is still working.
So, I would suggest clearing the cache and app data, then turning the phone off. Turn the phone on, update to the newest map version, then try it. If it still fails, clear cache and app data and try again.
