Fail To Do Year End Wizard

SUGGESTED

I using the Peach Tree 2009. At the beginning of this year, I want to do "Year End Wizard" close 2014, but at the last step "begin close", the progress is stop and non any respond. After I force close the program and reopen it, some data have problem, it only show the sales order and invoice from Jan-Mar.2015, the rest months are missing, the received payment and inventory are no problem. When I restore and verify the back up data, it's nothing problem, but when I do "Year End Wizard", it's appear the same problem.
