Hi,

I've recently been unable to open several of my key chartbooks. I'm not sure what happened.

The message on the log is as follows:

Error opening Chartbook file for determining internal version. C:\SierraChart\Data\ESF Chartbook.Cht. | 2020-09-18 21:36:19.818 *
The Chartbook file requires a newer version of Sierra Chart or is not a valid Chartbook. File: C:\SierraChart\Data\ESF Chartbook.Cht | 2020-09-18 21:36:19.818 *

I have the latest version of Sierra Chart. Most of my other chartbooks are still working. I cannot find any relevant documentation that addresses this issue and so I am getting in touch.

Thanks,

SF
