addition apologies check database default display few generating help knowledge log output problem purchase script serial serials solved suddenly thank-you-page touching weeks writing

I have a script that's generating serials, writing to DB, etc, etc.

I've used it without a problem for a few weeks now, and without touching anything (to my knowledge), suddenly, E-junkie does not display the Serial on the thank you page (I'm using their default thank you page). It used to just fine. My only output on the script I use it JUST the serial, so that's not the problem. In addition, when I check the E-junkie purchase log, it shows the serial there, as well as in my database. What's going on? ):

Any help is appreciated. :D

Here is the script:
