Is anybody else having problems with the latest version of P00SPDL?

I worked extremely hard to develop an EDD-BI application, which now works fine in my production environment.  Now we are in the process of upgrading to version 9.3.1.3 of World, and all of a sudden P00SPDL is throwing a "length or start position is out of range for the string operation error" at statement 202 on the call to BLDDWNLO.  And sometimes it dumps with a "Receiver value too small to hold result" error.   Oracle support will provide me with absolutely no help because my base RPG program has been customized.  As a customer, I find this extremely frustrating, incomprehensible,
