Cannot register for Rekordbox. Username/email already in use.

I am attempting to register for rekordbox. However it keeps telling me that every email I enter is lready in use (I have tried three different email addresses). Not only this, but I have tried several unique usernames, some of them utterly ridiculous (ahshfkjbfksbnf for instance) and the system still tells me they are ALL in use. Please help, gig tomorrow and beginning to flap.

Thanks.
