sql server restoring back up error

I have backed up a database I had created on an other machine running SQL server 2012 express edition and I wanted to restore it on my machine, which is running the same. I have ticked the checkbox overwriting existing one, and got this error:

Backup mediaset is not complete. Files: D:\question.bak. Family count:2. Missing family sequence number:1

This happens if, when you made the backup, you had multiple files listed in the backup destination textbox. Go back to your source server and create the backup again; this time, make sure there's only one destination file listed.

If you had more than one file listed as the backup destination, the backup is striped across them; you'll need all the files to perform the restore.

You can verify this by performing a RESTORE LABELONLY against the single file you copied to your destination server.
