Panel Builder 800 - can't open a project
i can't open project in Panel Builder 800 (ver6). When i try to open project the following information is displayed: "The '[' character, hexadecimal value 0x5B, cannot be included in a name."
I don't have such character in a project name. Yesterday I normally worked with a project and today, I don't know why I can't open a project. If someone has a solution that would be great.
