Nodes' Data Preview not working

DataPreview

I’ve made a clean install of DynamoInstall0.8.3.20150924T2050 and Data Preview of Nodes show null. And also Dynamo crashes regularly.

When I revert back to DynamoInstall0.8.2 everything works OK.

Has anyone experienced this?

Haven’t experienced regular crashes, but the ‘null’ is a regular. The null issue I handle by reopening the file.

Thank you Vikram for the answer. It wouldn’t bother me either if my dynamo didn’t act weird.

Will try to uninstall other add-ins to see if they are the cause…Screenshot 2015-09-30 12.05.29

To anyone having the same issue. I could manage to solve this by importing the Material named “Dynamo” into our template.
