We have a license for Aspose.Total. We renewed our license in August. We have upgraded to the latest versions of Cells, PDF, and Word. We also use Slides but because Slides didn't have any fixes for us, we chose not to upgrade it. With the new license and new version of some of the libraries, we seem to not be able to use everything as expected. We receive the message “The license is not valid for this product” when loading Aspose.Slides v18.104.22.168. Should the new license be backward compatible?
