Typically Root + OTA = Problems. You should not take OTAs when you are rooted. You have two choices:
--Wait for a rooted version over at XDA to flash (should be within the day) or
--RUU back to original software, then accept the OTA, then root
Of course with the former, you have to wait....The problem with the later is that you loose all your settings (but you get the bonus of a 'fresh' install, which may cure some issues if you've had them) and have to reinstall your apps. If you already have the red ! , you need to go that second route. Hope that helps you, or anyone else in a similar situation.
