Unable to use 'HoneyBee Run Energy Simulation' component

Dear HB and LB users,

First of all thank you to all those who post questions and answers on this forum. Things have been going quite smoothly for me for the last 6 months as a honeybee user, in large part due to the many selfless and super helpful responses on this forum.

I hope I am not doing something stupid here....but I am unable to get the 'Run Energyplus Component to show up among the components even though I see it in my src folder (Image attached). This only happens when I open an old file. When I open a blank new grasshopper session I see the component. How can use this component with my old file. Please help. I need to generate some idfs.

I have tried HB versions 0.0.59 to 0.0.62.

Thanks in advance for any guidance.
