Downloaded MSSQL backups aren't restoring locally.

I’ve download 2 different database backups (bak files) from the mssql2 backup page located here: mssql2.g********.com/mssql/Backup.aspx

When I try to restore to my local MS SQL Server instance, I get the following error. Note how it lists the selected bak file as “incomplete” in the list at the bottom. I’ve been able to restore one of these backups a few days ago, but somehow not working now. Perhaps it’s downloading incorrectly?
