I am receiving the following error right after the label prints while it's saving shipment information
"The file readed is not a valid "Portable Network Graphics" image because it contains an invalid header. This file may be corrupted, try obtaining it again."
Then Stamps.com shuts down, and my packing list doesn't print.
Help?
