NolaPro Free accounting error 0.7

Dear all,
For my work I am using Nola pro free Accounting software, and I am using it on my computer. I got a new HDD and on it I got Windows XP Professional SP2. Now I am having problem with Nola pro. When I input information for an invoice when I need to finish it error message appears. More than welcome will be any help? I don’t know what is wrong.
Error 0.7 is the error
Thank you.
Mitch
