As he booted up FlashFXP 5.4 build 3956, he noticed that the trial period had expired, and he was prompted to enter a license key. John had been using the trial version for a while, but he knew he needed to get a legitimate license to continue using the software.

He recalled purchasing a license key from the FlashFXP website a few years ago, but he couldn't find the email with the license key. He tried to search for it in his inbox, but it was nowhere to be found.
