You must upgrade to version 4.2.0.1 now!

I just published a new version of Book Me© that fixes a timing issue that had the potential to cause some attempts to get you an A to fail.  I have inactivated old versions to ensure that everyone updates to the latest version.  Old versions will no longer work.  You must upgrade to version 4.2.0.1 now.  If you have arrived here because the version you were using could not validate at sign on, upgrade by clicking here.  Thank you all for continuing to use Book Me©.  Please post your comments about your experiences with Book Me© so that others can hear what you think.
