Marcelo,
Versions earlier than MyEclipse 2014 are no longer fully supported. It is recommended to update to MyEclipse 2016, which is based on Eclipse Mars. The latest releases have lots of new features and several enhancements when compared to MyEclipse 10.x.
You can download the MyEclipse 2016 installer from here : https://www.genuitec.com/products/myeclipse/download/
Install MyEclipse 2016 to a different location alongside your existing MyEclipse 10.x installation and use your current license.
You can import the projects created in MyEclipse 10.x to MyEclipse 2016. The migration wizard appears automatically for projects requiring migration, but migration is not forced.
Please go through this FAQ for more details about Project Migration in MyEclipse ;
