BI Publisher Macro Error

I have worked on BI publisher few months ago. But today when I started to work again on BI publisher, it was not working. In add-ins tab of MS word 2007, when I checked any menu, it was showing error like The macro cannot be found or has been disabled because of your macro security setting. After googling, I have solved the problem following ways. I have searched *.exd file in my pc and renamed the exd files as back file. Then I have restarted the MS word 2007 and found everything is ok.
