All supported releases of DevTest

What can cause this issue is a corrupted file under the the $DEVTEST_HOME/vsBuilderSessions/VSE_2013 folder in the VSE Server. 

Or if exists lisa.user.properties file, then under the folder <dataDirectory_path_Mentioned_In_lisa.user.properties_file>/vsBuilderSessions/VSE_2013

• On the VSE server, make sure the VSE is not running.
• Rename the VSE_2013 folder under $DEVTEST_HOME/vsBuilderSessions. Or if exists lisa.user.properties file, then rename VSE_2013 under the folder <dataDirectory_path_Mentioned_In_lisa.user.properties_file>/vsBuilderSessions/
• Restart the VSE Service.
• The VSE_2013 folder will be recreated when the VSE starts.
