Greg,
Thanks for providing the details.
With this license, can we update to the 2014 version?
Yes, you can upgrade to MyEcllipse 2014 and continue using the same license which you have used for previous versions of MyEclipse. MyEclipse licenses are time based, not version based.
I suggest you to try our latest version MyEclipse 2015 CI, which is based on Eclipse Luna. MyEclipse 2015 CI is a unified MyEclipse product with license levels allowing you to access all MyEclipse features. Instead of downloading and installing separate products (MyEclipse Blue, MyEclipse Spring or MyEclipse Bling), the license level you purchase provides you with access to features such as advanced WebSphere and Spring, all from one product. With MyEclipse Continuous Integration Stream (CI), you will have access to new features and important fixes without having to wait for a GA release. MyEclipse CI releases will receive frequent updates as development progresses towards our GA release. You can download MyEclipse 2015 CI from here and give it a try.
Regarding configuring the license, after installing MyEclipse 2015 (or 2014), navigate to <MyEclipse installation dir>/plugins/com.genuitec.myeclipse.product.meXX folder, open plugin_customization.ini file in a notepad, navigate to end of the file, add the following lines (with your Subscriber Id and Code), save the file and restart MyEclipse. After restart, you still need to activate MyEclipse using any of the methods mentioned here.
