Sathya,
Thank you for buying Angular IDE. Glad that you figured it out. Currently Node.js versions 8 and above are not supported for language services. Please note that you can create projects with Node.js version 8 and higher.
Can you please clarify if you are working with the latest release of Angular IDE i.e CI 11a? You can check the version details here : Window > Preferences > Webclipse. If you are working with a release older than CI 11a, then please go to Help > Check for Updates and update to CI 11a.
Please let us know if you see any other issues with Angular IDE.
