Running MyEclipse 2015, Rhino version1.6.
I suggest you also check with development related forums like stackoverflow.com for better support from the developer community.
Please note that versions earlier than MyEclipse 2016 are no longer fully supported. If possible, please update to the latest MyEclipse 2017. Your current license is valid for newer versions as well.
The latest MyEclipse 2017 installer is available for download here : https://www.genuitec.com/products/myeclipse/download/
Hope this helps. Please let us know if you see any issues.
