Mike,
Sorry that you are seeing this issue. Versions earlier than MyEclipse 2015 are no longer fully supported. We try and assist licensed users working with previous versions but no fixes will be made to those versions.
MyEclipse 10.x is quite an older release and is unstable when compared with the newer releases. I strongly recommend you update to MyEclipse 2016, our latest release based on Eclipse Mars and take advantage of the several fixes and enhancements made since the MyEclipse 10.x release.
You can download the latest MyEclipse 2016 installer from here : https://www.genuitec.com/products/myeclipse/download/
Install it to a different location alongside your existing MyEclipse 10.x installation and import your projects. The MyEclipse Migration wizard will take care of the projects migration process. The license you currently hold is valid for MyEclipse 2016 as well.
Let us know if you see any issues.
