Restore SQL database

I'm attempting to restore a backup of a database as another database -
so I can access the data in the backup file and transfer some of it to
the existing (operational) database.
However, when doing this, I get the following error:
"Cannot open backup device 'x:\file path on server'. Device error or
device off-line. RESTORE DATABASE is terminating abnormally."
This is the second time this has happened, despite the fact that the
backup device is on-line.
Yet I was able to perform the same operation a couple of days ago! Any
ideas?
Is the path a local path or a remote path? Is there any chance that another process might be using
that file (AV software, or SQL Server itself currently writing or reading that backup file)?
