As with all software, bugs were found, and strengths were improved. This led to the release of UPDs (Updates).
These updates were crucial. They tweaked the engine's evaluation functions, making it play openings more soundly and endgames more precisely. However, installing an update created a friction point that frustrated many users.
The update system often required the user to re-verify their license. Furthermore, because Deep Fritz 12 relied on the "ChessBase Dongle" protection method or an online activation server, users faced a common headache: if they reinstalled Windows or upgraded their computer, the key would sometimes be rejected by the server, which thought the software was being pirated onto a second machine.
Users would scour forums, looking for the "UPD" files to bring their engine up to version 12.x, but the moment they applied the patch, they would be locked out unless their activation key was perfectly in order. This created a sub-culture of users looking for ways to bypass the activation, often leading to malware-ridden "keygens" that promised to unlock the engine but often infected PCs instead.
