: Cracked versions often use "loaders" that attempt to freeze or spoof the system time to keep the "trial" active. If the loader fails to hook into the Windows kernel correctly, this error appears.

Even with a legitimate WinOLS license, the error can appear if your Windows OS has date-related problems. While setting the correct date via the taskbar seems obvious, the underlying system can be corrupted.
