Panelbuilder 32 Problem

Good Morning.

I have an application running on a panelview 1000 which was created using version 3.81. I am trying to open it using version 3.80.

I keep getting an error telling me the file is either corrupt or not a panelbuilder 32 application. I can upload from the panel but not open the file. Is this a version or is there another issue?

Thanks Joe

Ya, you cannot open a project that was created with a newer version.
You can download the newer copy from Rockwell if you are enrolled in the support program.
