Fear not, help is available, please see the post in the Forum thread: Frank Zappa Halloween 77 Box Set Details clarified please.
There you will find a post from Gray Ghost giving you an email where you can send a photo of your box set and they will be able to help you obtain your tracks. Currently it's for 1 track that is believed to have a minor error(myself I didn't have any problems at all but it's good to note there's support in any case).
So stay calm and keep enjoying your Zappa fellow fan.

Finally to conclude, no it does not Suck, it's just that the release is so brand spanking new and this is the first time such a release has taken place. Fear not, I can personally guarantee this is one of the finest Zappa releases I've ever heard. Amazing value and all 6 shows are magic.
