Usually when I see this, qRules has been disabled because custom code was unintentionally added to the form. Easy test is to put the Command and Result nodes on the form, preview and type in GenerateGuid for the command - do you get a GUID in the Result node?
When I look at your form, it does appear code has been added - see screenshot attached. If it is not intentional, click the Remove Code button to remove it. If it is intentional, there is a document here on how to use qRules with your own custom code. The document has not been updated for the new dev environment with IP 2013, so let me know if you are using 2013 and the custom code is intentional.
