Red window Asking for activation

[Mario Arizmendi Duarte]

Since last days, the app (free edition) is showing me a red window asking me for activation, I proceed to introduce my user and pasword, but it tells me wrong user or pasword even if  I am completly sure that I am introducing it correctly...

Was wrong, what can I do?

 

Thanks in advance for any response
