Hi All

I am receiving a runtime error: Wrong array index. Please open Callstack. on wago software.
When I open callstack, I cannot find the error.
This software was written in 2008, and was working. I am busy reloading it as the PLC cpu was replaced, but now will not run.
I have attached the pics of the error and the pointers.
