VACO is not counting (Runtime event: "Embedded Software missing: VACO")

[Anas_FAISAL]

Hello,

I am starting a fresh project in Zenon Logic. I connected two counters to a VACO function block.
However, the VACO counter is not counting and the Runtime event viewer is showing "Embedded Software missing: VACO"
What could be the problem? 
thanks in advance.

I am using Zenon 8.10, from within which I openen a new Zenon Logic project.
It might worth mentioning that I am using the Demo mode, not sure if that might have an effect or not.
