"License ID" and "License Password"?

Hi

I have just downloaded to newly released X1 8.0 and it prompts me to enter the "License ID" and "License Password". I only have ever received an "Activation Key" from X1, so I have no idea what to enter here. I have tried various combinations of activation ID, email address, name, forum password etc. without success. Image may be NSFW.
Clik here to view.
