Sorry about that. I have sent you credentials to the D/L page.
I still don't know what happened to the PayPal IPN interface to the site, or if it is on my side or theirs. I'll look into it when there is more time and it can be scheduled.
That said, I was able to manually send your customer credentials for the glossary D/L page. These should be good for a year barring their inadvertent publication.
Again. I'm very sorry for all the hassles.
