-DUPLICATE-WL-crashes-with-MissingMethodException-in-Analysis-Series-after-update-to-B37

Hello,

I have just run the build 37 update and none of my existing strategies are working. i have tried several and keep getting the same or similar error message as shown below.

How can this be fixed?

Thank you.
