Hi Mohan,
Thank you for contacting us regarding this issue. We are sorry you are running into this issue. The license key associated with this user id should not be giving you an activation issue. Could you send a screenshot of the the license you are entering into software to sales@genuitec.com? This way our customer service team can look into your situation without your key being posted on a public forum.
Thanks So Much
