PC players attempting to play The Walking Dead: Season 2 have run into trouble while trying to authenticate their game key with Telltale's servers.
According to numerous reports on the developer's support site, multiple users have reported issues with the servers failing to recognise that they own the game, and receiving a message that tells them to "go online to telltalegames.com and buy game, signout or exit game".
The issue is thought to affect users who purchased the game through Telltale's website and via certain third party distributors, including Greenman Gaming.
Steam buyers are not thought to have been affected.
Telltale since claims to have "solved the server issue" thought to be preventing users from properly authenticating and apologised for the issue.
"We have now solved the server issue," Telltale wrote on its support site, "please restart the game and attempt to log in again, and the issue should be resolved. If you are still experiencing log in errors, please reply with what your error message says, and whether you are on PC or Mac, and whether your [sic] on Steam or playing through Telltale. I apologize for any inconvenience this has caused."
But while the issue appears to have been solved for some, other users are still reporting problems, and Telltale is adamant that it will not be offering Steam keys as a solution to those affected.
"We currently are not giving steam codes to customers that purchase through our website," the developer wrote. "I apologize for the inconvenience."
Telltale has been criticised by consumers and critics in the past for the numerous technical issues associated with its games. The first season of The Walking Dead was particularly criticised for a bug which saw players' game saves and decisions failing to carry over to subsequent episodes.
The Walking Dead: Season Two launched yesterday on PC, PlayStation 3 and iOS, and releases today on Xbox 360.
