Hi, I am trying to open a dynamo script but the nodes seem to be missing. I see a similar post a while back about removing all packages, which I have done but no success. Dynamo version is shown on the image attached and Using Revit 2017. Any help would be appreciated!

Thanks - Darryl
This is interesting, have you tried opening the script on another computer? Maybe you could upload it on the forum.
Also, is your dynamo file stored in a cloud? This could create problems.
Try disabling all Revit add-ins and see if that resolves it.
This is what I’ve had to do previously, I couldn’t quite put my finger on which add in was causing the issue. But stantec has an app that allows you to temporarily disable add ins for Revit.
Hopefully it helps!
When i try opening your script i get instantly an error message telling me that you have some corrupt nodes in this script. I do not know what causes this problem nor how to solve it but maybe somebody else knows
