An expired licensing key error can appear in Adobe's Creative Suite 5 (CS5) for a few different reasons. If a pre-release copy of the program is downloaded, the key will expire when the pre-release period has officially ended. The same reasoning is also true for trial versions of the program. Once the trial period ends, the trial key becomes null and void. The error can also occur if a new product key has been requested. Upon requesting a new product key, Adobe customer service automatically deactivates the current key to prevent illegal use
