I get error tagging Grilles and Diffusers using DGAnnotation.

Hello

I am using Aecosim 08.11.09.829. I am on my final stage of my project when I encountered this very huge issue,

I am about to annotate my diffusers and I got this very strange note in my status bar.

it says:

ERROR!!! Unable to find active cell. 

I even tried to add it DG Annotation Cell but still I get the same issue

Thanks a lot,

Vince
