High Performance Loader HELP

I have been using the High performance loader (HPL ) version 7.2 on an HP-UX 10.20. It has worked fine in most cases, but when I have to create a large project it gives me an error and creates a core dump. I spent a great deal of time with the Informix technical support person who was very helpful and it seems that the problems that I got are reported errors in this version. My question is if some body has an SQL script that will remove a project with all its jobs and dependency tables from the onpload database. I can not remove the projects from the ipload GUI because I get an error and a core dump (these were the projects that I had problems with). Otherwise could I just drop the entire onpload informix database and re-create my two projects that do work? Thank You very much
