When trying to upgrade firmware, receive "Bad file signature. 'NV123XA-18-01-06-00.biz' is not a valid image.

This is a brand new Adtran. I'm going to Adtran's site and downloading the firmware for an Adtran NetVanta 1234P PoE and receive the following message when trying to select the .biz firmware files downloaded.

I tried the following firmware images:

18.01.06.00	NetVanta 1234/1234 POE/1238/1238 POE Firmware	3/15/13	Release Notes	Download
18.01.04.00	NetVanta 1234/1234 POE/1238/1238 POE Firmware	10/19/11	Release Notes	Download

But I receive the message: "Bad file signature. 'NV123XA-18-01-06-00.biz' is not a valid image.

Yet, it won't take either one. I tried to re-download. Any thoughts? There looks to be 15MB free in flash and these images are only 5MB each.

Nevermind, of course right after I register and open my mouth, I go back and take a look and see I was downloading the firmware for the first generation 1234P's. 2nd Generation 1234P firmware took successfully.
