ERROR [AbstractTestRunner] Exception during Test Execution

I deleted my workspace file.
I created a new workspace then i imported my project in this new workspace but i see again the same error message.

<?xml version="1.0" encoding="UTF-8"?>
<con:soapui-workspace name="V3Workspace" soapui-version="5.5.0" xmlns:con="http://eviware.com/soapui/config">
  <con:settings/>
  <con:project name="V3_DolmenWebServices">/Users/aurelien.galpin/ProjetSoapui/DContactV3-soapui-project.xml</con:project>
</con:soapui-workspace>

I think that the XML file project contains old properties based on version 5.4.0 SOAPUI.
Extract of my projet.xml
