Firmware Updater

So, of course I’ve had my My Book Essentials for 5+ years without issue. Tonight, I need the firmware updater and come to find out that lifecycle was up until 2 days ago. Does someone have a link where I can download it tonight because somehow my drive is suddenly set to not allow me to delete anything off the drive. I have an admin account and permissions SHOULD be set to allow it but nothing will run and the entire premise of this drive was to backup everything. I have a WD My Book Live that was supposed to have everything sync, but somehow that stopped happening a month or two back.
So any advice on how to proceed would be nice to hear (other than format and lose it - which is why I have the built in redundancy in the first place after losing single backups in the past).
