Deleting an old purchase invoice

I'm using Peachtree Complete version 8.0 (I know it's old, but no budget for new software).
I still have 2007 open and am doing some clean up prior to closing it
so I can do 2009 transactions.
We used to have this dental insurance and entered a purchase invoice 6/1/07. A check was printed to pay it on 6/8/07, but before it was mailed we decided to drop the insurance. I found tonight that the check had never been voided so I voided it as of 6/8/07.
I went to the purchase invoice to delete that, but the option is greyed out and now this 18 month old invoice pops up when I run "Select for Payment". How do I get rid of the old invoice (and I have to do it fast because I have to close 2007 by tomorrow evening).
Thanks,
