A recent windows update updating .NET 10.0.10 to .NET 10.0.11 appears to break the report viewer in both GMoor and GM Opsim. We are at the present time not sure whether the change was intentional on Microsoft's behalf, but we have some clients, as well as internal users that has had troubles with the report generation in the two software.

We have pushed new releases of the affected software, so if you experience the error, please try to upgrade the installed version. If you still experience problems, reach out at support@globalmaritime.com
