We keep getting an error message when starting the program. It says "*.lng file not found" see also the attachment.
In case of any abnormal operation of VideoCAD 8 please first of all save your project to a file. Main menu>project>Save as. During saving special checking and correction procedure of the current project is performed.
If it does not help try to uninstall and reinstall.
If the error remains after reinstallation then the most likely it is a registration error caused by antivirus or other guard software. Such errors can happen at the first launch after installation. You need to reregister by other code with all antivirus stopped. Please contact by email to get other code.
Other known reasons of errors are unsupported AutoCAD files used as background (try to delete background) and new imported 3D models (try to delete them).

Besides that sometimes it becomes very laggy, almost not workable, when looking at 3d views.
VideoCAD offers powerful but resource-intensive tools, which can be enabled or disabled. Disable heavy tools when you do not need them, especially when you work with complicated projects. You can enable these tools before saving or export.
When you do not need modeling of image resolution, illumination, DoF, exposure...etc., - disable image processing in the
3D Video window.
Main menu>Speed>Disable image processing.
In the
3D World window enabled visualisation of camera coverage can slow VideoCAD. Especially when you show it with high resolution and Dome mode or fisheye cam. It is very good visual tool but it is heavy.
You can adjust its resolution by the
Resolution combo box on the View tab of the 3D World window. You can disable it when you need not it by the
Coverage checkbox on the View tab of the 3D World window

If VideoCAD becomes slow with even simple project, the reason is an antivirus. It intrudes into processes and makes operation slow. Try to stop antivirus and add VideoCAD to it's white list.
