Wow! I should have posted here earlier. Here's what happened:
1. Server logs got out of control and filled up the server's hard drive.
2. Last modified info was erased, so everyone who logged on within those 2 days was erased.
3. CCBill finally rebuilt the password file correctly.
4. All is well.
I became tied up with work and was unable to check email for a day and when I did it was flooded, so it took a while to catch up figuring out who was locked out or what reason.
So there's the "behind the scenes" info on why that all happened. Thanks for being patient 🙂
