I have no affiliation with Lone Wolf, and I've never used Army Builder, but based on
this 2015 Wayback Machine snapshot, that site is not under Lone Wolf control (probably purposefully to help insulate them from lawsuits), and is run by Robert Lantry. Unfortunately, the provided support email address is for the datafilecentral.com domain, so we can't exactly reach out to him.
It could also be this is a temporary domain loss... said domain is currently for sale.
