Hi, this is a weird one.  I've been pulling up a bunch of older files for a newer computer and I just came across an invoice with three missing products.  That is to say, the items are listed, but there are no files attached.  There are other items on the invoice that do have the files, but it looks like somehow these three products were flipped to a negative price, though the price on all three is so small that it couldn't have been a product return, and in any case, all three items show up in my products purchased library.  The invoice number is 112907970, dated August 25, 2016, and the missing items are "Tribal Flames", "Rhinestone trims" and Brushes - Music," all from the same vendor.   Any help would be appreciated...
