Illegal camera type in camera parameters

The following error comes up when I open a previous project.

“Illegal camera type in camera parameters.”

Is there a solution other than starting over?

thanks

Hi Ken,

I’m sorry this has happened to you. We’re currently investigating a similar problem from another customer. If you can zip up and send us your project file, autosave and autosave.backup files we will try to recover them and this might also help us pinpoint the problem causing this.

Please mail the files to support AT imagineersystems.com

Best regards,

J-P

Does anyone have a idea as to why this is happening?
thanks
