If you had our updates installed, it would be a simple matter of setting the dates in AM-N for the current and six years past.  However since you have the original DBA version that is limited to 3 years and assumes 12 month years it will be tricky.
 
If July 2012 is the beginning of your second short year and you haven't posted anything in July and you are finished with June then set the AD-A fiscal year start date back to 7/1/11 (ignoring the message warning you not to change the date) and run AM-B to generate the YE entries for 6/30/12 and reset the new FY Start Date to 7/1/12.  Come 12/31 you will need to do the same sort of thing.  If you have already posted in July, you are kind of stuck.
 
Or you could load our updates and eliminate the whole problem.
