Hi Macit,
Thank you for evaluation of the LookupPal.
You right, all users of current promotion use the same key RDG1L-6IG8A-3NX4C . This key is active during the promotion and supports unlimited number of activations. For example today 25 people used this key to activate the LookupPal. All activations succeeded.
What message did you see on the screen? Why you think that key RDG1L-6IG8A-3NX4C is inactive?
