Sony's latest PlayStation 3 firmware went live on Tuesday, but the update that was meant to improve system stability instead left a number of users locked out.
Players took to the official PS3 Support forum to report the issue, saying that they couldn't reboot their system after the 4.45 update.
Sony quickly responded to the complaints via Twitter, writing on the PlayStation Europe account that it is "aware of reports" about the recent PS3 update problems.
"We have temporarily taken 4.45 offline and are investigating," Sony said. "We will announce when the system update is available for download as soon as possible and we [apologise] for the inconvenience."
The latest update available on the Sony PlayStation site is version 4.41, released in late April. Version 4.45 was supposed to let users choose whether they wanted in-game notifications when they earned trophies.
A second forum topic was posted afterwards, discussing a possible fix. But the best instructions available simply warn users not to do a system restore and wait for the release of a fix.
The company provided us with an official statement similar to its earlier tweet: "We are aware of reports that the recent PlayStation 3 system software update (version 4.45) has caused the XMB to not display on a small number of PS3 systems. We have temporarily taken 4.45 offline and are investigating the cause of the problem. We will announce when the system update is available for download as soon as possible. We apologize for the inconvenience."
The firmware glitch comes hot on the heels of Sony's strong showing at the recent E3 gaming conference in Los Angeles, where details about its upcoming PlayStation console were revealed.
