Recently I have been having issues with updating my BIOS (and frankly anything for that matter).  Anytime I try to run the update utility I get an error message of "your security settings could not be detected.  Try restarting your system and running the update again".  No amount of restarts and uninstalling and reinstalling Dell's update utilities and the like has fixed the problem.  I don't recall doing anything different that would have prompted this so I'm pretty stumped on this one.  Any suggestions are welcome.  I've attached a screenshot below.  

Thanks
