The Serial Number Of Photoshop Cs5 Extended Serial Numbers
The error "The license for this product has expired" is unrelated to the error "Licensing for this product has stopped working." An expired license means that a serial number, which is no longer valid, is still stored in the pcd.db database file. The valid serial number you received with your purchased product didn't overwrite the expired serial number during the installation process. Removing the expired serial number allows you to enter your valid serial number.
