@Jeanjean: Can you please drop a mail to firstname.lastname@example.org? I can confirm we got auto-reported this error already. It is unrelated to your activation. Throughout huge number of today’s activations your computer was the only one (until now :) that throw that SQL related error. We will try to follow up and get it to work on your machine too. Please drop a mail there and we will react within few hours. Thank you!
