[Steam Old Client Error Issue]
We have identified an issue with the 'old client error' occurring for Steam accounts that have been inactive for an extended period.
Typically, if a Steam account has not received game updates for about six months, an 'old client error' message appears, and in such cases, we recommend reinstalling the game.
However, we have identified error issues with the reinstall client and are working to address this.
The Steam client's re-installation files will be updated on the upcoming maintenance date, August 31st.
We apologize for any inconvenience this may have caused.
Regards,
Shadow
