@dhirajv12 Let’s double-check some things. Please enter the following.

cd ~/MagicMirror rm -rf modules/aiclient git pull npm install cp config/config.js.sample config/config.js npm start

With luck, that should at the very least get you a basic interface with the calendar, clock, compliments and newsfeed.

@dhirajv12 said in Black Screen after Launching application.:

In the terminal it says
No helper found for module: clock
no helper found for module: complements

This is normal. The system is checking for a node_helper.js file for every module. Those modules do not have one, so it is reported as such during the startup process.
