Hello,
sorry we are back from the holidays today. We'll read all the last messages.
About your specific question (to change the domain name), we have spent many time to explain that the change is allowed only if the modules were not present on the previous domain. You have removed the modules from the previous domain on August 27 and we have sent the new code on the same day.
We'll write to you in PM to communicate the email address and the codes for the modules.
