SHIFT problem (solved)

Changing my initial comment: I could not activate the SHIFT 2015, KIS will offer no entry for the new activation code once the SHIFT installed.
A little problem but in reality poorly documented: just off the old key that remains active despite Update and blocks the process.
Click on the little cross on the right of the old key to delete it, and then we can enter the new key.
Thank you to the friendly and efficient service Kaspersky.
