Cannot post time in a previous year in Amicus Accounting

Sometimes a client will install Amicus Accounting and want to start posting their old time to it.  If this time is in the previous year, you will not be able to post.  To fix this issue, make sure everyone is out of Amicus Accounting.  Go to Start Up --> System Settings and Change the Financial Year Start and End Date to the previous year.  Post all the time for that year and change the settings back to the current year.
