Have you called Amtrak and explained the situation? They might be willing to void the first ticket, and issue you another with a confirmation number you could use to verify the purchase when you arrive at the station that morning. I know you have had terrible problems with Amtrak in the past, but it might be worth a try, Serenity.
You cannot be the only person something like this has happened to.
Other than that, if you look online you will find the location of the local branch of the Public Library where you are. Call first to be sure they have internet access and printer. (Usually, they do.) Then, just call the ticket up and reprint it.
Take care, Serenity.
