I have found an issue with this 7D firmware version 2.0.3, that I am no longer able to register focus points. I hope that Canon will solve this major issue.
Did you completely cycle the power after the update? Remove the battery for a while to erase old memory settings and ensure the new firmware is properly loaded.
