If you own a genuine WinOLS license (dongle or online activation), contact support directly:

You lose the ability to purchase official OLSX resistor packs, map packs, and damaos files directly from EVC.

If your setup requires a frozen date, completely disable the Windows Time Service ( w32time ) via Windows Services ( services.msc ) to prevent background updates.

If you are running an older, offline version of WinOLS that relies on a specific past date to bypass an expired timestamp check, changing your system clock manually every time is tedious. It also breaks your internet browser security certificates.

Expired configurations or temporary cache files inside the WinOLS directory are throwing off the software's internal calendar.

Your computer’s motherboard battery (CR2032) is dying, causing your Windows system time to reset or drift every time you power off your PC.

The error is a protective mechanism, not a bug. It is designed to prevent license abuse, but it can mistakenly lock out legitimate users due to hardware failures, time sync issues, or file corruption.
