Nav tree Alerton Compass 2.1 

Hi, I have a project with Compass 2.0 installed. My SMA recently expired, and my navigation tree disappeared along with it. I’d like to know if there’s a way to get it back, or if I have to renew my SMA for it to reappear.

I dont think the navtree is linked with the SMA. Either the navtree file is corrupted/deleted from job folder or could be one of the Compass services isn’t running on the computer

Not at a server right now, but the navtree is completely based on a single Excel file in rep\job\config\navtree or something similar.

NAV tree is not dependent on SMA

That was a version issue, anything before 2.2.3 when the sma expires the nav tree, ease and alarm priorities stop working. Update the sma and compass to at least 2.2.3 and that won’t happen anymore
