Unable to download new profile, get 80150016 xbox live error

Xbox 360. Bought game and needed a live Gold account. Bought 1 year Gold membership. Tied child account to parent account. Parent account already on the Xbox showing "Live". Worked with Support to get the 25 digit Live Gold number in the system. Since
child account has to be linked to parent, when signing in to download a new profile, we use the parent account to sign in.

We created a new profile on the Xbox for the 2nd child.

When choosing, "Download a new profile", the Parent account name and the first child account show up as already in place on the USB attached. (32GB USB attached for more storage)

The new account name for the second child is listed, but does not show that it is anywhere. When selecting the second child account in the download section, I immediately get the 80150016 Cannot download error. We are choosing the USB because the System
memory that is in the Xbox is almost full and we are attempting to put the new profile on the USB.

It does not start to download, it fails immediately.

Cleared the cache on the machine 3 times with accessories unplugged. Same problem. At wits end!
