My question(s) on which I really need help:
1)is the lack of a PDT so far a possible reason for not getting order details within and from the cart?
I have seen ver 1.3.8 and above the PDT field it says"
Enter your PDT Token value here in order to activate transactions immediately after processing (if they pass validation)."

BUT if so, why have most orders been coming through despite not having pdt setup?

2)If I do NOT upgrade to 1.3.8 (have lots of mods), will the fact that I have now setup PDT in paypal cause additional problems?

3)Is there some patch that can be applied to integrate the PDT part instead of doing a full upgrade? If so, where can this be found?
thanks, thanks and thanks!
