vCO-CLI fling Start Session failing

I'm running vRO 7.0.1.3533702 and have installed the vCO-CLI fling but the Start Session workflow fails to start, the error is as follows:

[2016-06-09 13:36:54.095] [E] Error in (Workflow:Start Session / Scriptable task (item1)#12758) ReferenceError: "CliConnector" is not defined.

Can anyone help resolve the above?
