Click on activation link from draftsight failed

Hello to the community. 15.10.2017

I installed the Draftsight, I was asked for my e-mail - I submitted my e-mail. (the Draftsight shuts down immediately after and I don't have the option of using it 30days without registration)

I received the e-mail from Draftsight with activation link:

"To complete the product activation process, please click here."

However when I clicked the link I got a message:

Error

There was an error process your registration.

Visit the DraftSight Community and review the iQuestions for possible solutions, or to report a problem

 

Please is there anyone who can know why I got this message?

(I try 2 different e-mails, got the same ERROR message.)

Thanks for any help.

 

Update: I tried the next day and the activation was successful.
