My error occurs when trying to log in. The password is correct, but the error persists. I also tested it on a laptop with Windows 11, and I didn't have the error there.David wrote: Thu Sep 24, 2026 7:33 pmDid the error occur after you started a new game or loaded a save game?wesleyfit wrote: Thu Sep 24, 2026 4:21 pm im having error in the file. version 12.0.86

Did it occur randomly or upon clicking a certain button or UI element?
What was the version number of the Capitalism Lab build you were using previously?
Please try installing the full installer v12.0.86 from viewtopic.php?t=10642 and see if it resolves the problem.
I performed the requested installation, and the error continues.
