3D FlipBook - Issue Obtaining Latest Version of 3D FlipBook Pro

Hi, I can't update the plugin automatically through the WordPress backend without receceiving the error message "update failed: Download failed. Forbidden". Our payments are up to date and we got charged recently so I don't understand why we're experiencing this issue. I also tried the link in the receipt and that plugin download is a few versions older. Can you please provide us the most up to date version?

Thank you!
