I had the same problem (as REDS1949) with the latest update to Chrome (30.0.1599.92). I would open Chrome and it would immediately close. In the Application Manager I tried clearing the data/cache for Chrome - it didn't help. Finally I chose to "Uninstall Updates" for Chrome and then let it re-update through the Play store. That seems to have fixed things and Chrome is working normally now. Since updating to 4.2.2, I've had to uninstall/re-install a few applications to get them working properly...
