errormessage: "Number of activations exceeded"  though I only use 2 devices.

Thank your for helping me with this issue.

I had to reset my mobile phone and my tablet and now this message appears on my mobile phone:

"Number of activations exceeded"  though I only use 2 devices.

I use Mantano reader premium.

Kind regards,
