I'm new to Zen Cart and want to say thanks to everyone for posting. Installed the latest 1.3.8a, and the latest FEDEX module 1.3.7 which seems to be working OK.
I followed the notes in this post thread and also made the changes per thread:

and thread:

I can't say if the prices are correct as I have not done any comparison. Can't say about heavy packages either. But I can say it seems to work on estimator and checkout screens. PayPal Express Checkout is not automatically selecting cheapest method. I think I need to add the "add cost per weight" somehow as that above thread discuss. Right now I just have 0:0 setting for both Configure -> Shipping/Packaging rows.
Thanks everyone. I called the FEDEX people as well and they told me about the management policy changes that occurred 1 month ago:
New system is "Web services" - old system is "Web Integrated Solutions". The old system has stopped accepting new customers. It's possible the FEDEX guy on phone did something to enable ... but I don' think so. Think he just watched as I configured the ZenCart FEDEX module. He didn't tell me he did anything special.
For initial setup, FDEX Express, I just used the "NONE" for Fedex Meter ID field (I alreadey had a FEDEX Account number) and then after doing my first shipping estimation I went back to admin module and the Meter ID number magically appeared! Then I used that number for Fedex Ground. This was really my big confusion and all seemed to go smoothly. Thanks again everyone.
Hope someone makes a newer FEDEX module that uses the newer "Web Services" technology. And perhaps a new module that does the printing of package label with bar code, etc. For now I will use the generic FEDEX stickers and book and do that by hand. I'm very low volume anyway.
