Thank you for your reply.
No, I cannot use the current version. I started development using the 5.0.017 sample source and I've made changed to and have fixed many bugs in the source. Integrating my changes into the current version would be a nearly impossible task. However, I was able to find an untouched copy on an older development machine and will be making a permanent backup. I would suggest that you do keep the older versions archived on your site. Thanks again.
