Additional Zoho Project instance created when trying to link GApps to existing Zoho Project

**** I have tried emailing this problem and raising it in more than one forum, is someone going to at least do me the courtesy of replying? !!!!! ****

I have added Zoho from the apps marketplace, I clicked on the button in an email to create a task and have ended up with a 'free' zoho account for a domain ending dotcodotuk. I don't want this, I need Zoho to reference my paid-for account asap. I need to rectify this as soon as possible so are there some instructions around I can get on with?
