Good afternoon, I'm new here in the forum and need your help. When I try to open a file in Caesar 5.20 I get the error Annex. This comes with any file I open. Download an update that is on the page but the error occurred.

Go to the "Configuration Module", the "graphics settings", and change the setting for the video driver from "OPENGL" to "Basic Windows Vide". See if that solves the problem.

Excelent Richard Ay! Thanks you very much... work fine finally.
