For starters, you are extremely brave to transfer all of you clients on the first day that the software is available.  Lacerte had some major bugs in its organizer when clients were rolled over, so it would be a surprise if ProSeries worked perfect on the first day.  I would delete the clients and try transferring them again.  If that doesn't work, assume it is the first bug of the season for ProSeries and wait for an update before you try transferring them again.
