Why Do I Get "Error During autorouter preprocessing. Invalid Polygon Data"?

Primary Software: Electronics Workbench>>Ultiroute
Primary Software Version: 8.3.7
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem: If I start the Ultiroute I get the error I get the following error message:
"Error During autorouter preprocessing. Invalid Polygon Data"
The problem results from an invalid association between existing copper polygon and its net.

Solution: To solve the problem, delete the corresponding net in the Netlist Editor and add it again. Now you should be able to route the design.
