Welcome back pradeep,

Given that you did not delete anything by hand all your data should still be available in the <user-home>/.klaros folder.

You just need to install/update Klaros and all your projects and test cases should be available again.

Just make sure you are using the same user account on your machine. If you changed your machine to install the software on make sure to copy the above mentioned folder to the new machine.

Please let me know if this works for you. If you run into trouble please add more information.

Kind regards,

Torsten
