What's the exact command you are using for the log backups?
I'm going to guess that you are doing this:
BACKUP LOG ... WITH NORECOVERY
That will back the log up, then take the database into a restoring state. It is not a normal log backup command, it's a tail-log, used only for when you are just about to restore the entire database from a backup.
