How to edit interactive tree?

[yhc_90]

I've built an interactive tree, but I needed to make some changes. When I opened the interactive tree, my tree was gone. I only have the first node. How can I edit an interactive tree without losing everything?

I'm using SAS EM 14.1.

Might need some more details since it normally should be there when you re-open the Interactive window.  Just be sure if/when you re-run the flow with that Decision Tree node in it, you set Use Frozen Tree to Yes so it doesn't wipe out your interactive modifications.
