I had an email from John Hung at Gigabyte appologising for the delay and telling me they are sorting out the certificate for it.
I don't have too much of a problem with waiting - we've got 3 years of warranty before the extended warranty has any effect.
As with a lot of things, when something new starts up you can get teething troubles - if you've not had anything in a few days again I'd say post here and I'm fairly sure runn3R or another member of the GBUK team would have a look and get back to you.
