I HAVE A SOLUTION

I have figured out a work around to this! I have no idea why this error shows up, but this seems to be a good fix. 

When you have the receipt pulled up for review, use the snipping tool and create a snip-it of the receipt. Save as a JPEG. Now use the upload by file option (it's a cloud) and upload the JPEG. Fill out like normal and save to register. Delete the old receipt that doesn't work.

Hope this helps!! It's so annoying that we spend all this money on this software only for it NOT to work
