Ravi,
Thanks for your quick reply.
a) I did check the variants, everything is correct and it doesn't appear that they have changed anything.
b) I tried to print it again. Only the Payment Advice (not the DME file and Payment Summaries)
When I check the job log for the print job, there is no spool generated.

Clik here to view.
When I check SMX, it says "No list generated"
c) No the client doesn't email the payment advices.
