Unable to open Interactive Decision Tree

Hello,
The following error message appears when I click the Interactive property in the SAS® Enterprise Miner™ Decision Tree node. You can see the whole error image below. I also get the same exception when try to run the predecessors to this node and update the path. I am unable to resolve this problem so I need your assistance to fix this issue. Thanks.

Exception
Unable to open Interactive Decision Tree. The Decision tree data set is missing. Please make sure you have run the predecessors to this node and update the path.
