Re-activation

I was recently asked to reactivate DraftSight before opening the program, I filled in all the requested information and receive the email which said I had successfully re-activated my account and not reply to the email. I tried to open the program again and it says to click on the link in the email to complete activation before opening the program. I went back and clicked on all three links, investigating each page finding no further instruction, I am still being told to click the link in the email in order to complete activation. Am I missing something here?
