updated from 10.8.13 to 10.9.3 - now I can't get server to start

[Paperkite]

Updated to 10.9.3 today. which required me to update .net framework. this required me to update windows which hasn't been done in a long time. 
anyways now i can't get the server to start.  below is the log.  Any help would be greatly appreciated! 

looks like the database might be corrupt. Any known fix? If i have to start over is there a way to keep all my settings?  I'm not sure what's stored in the database.

Thanks again.

Did you stop Jellyfin before upgrading? Do you have backups or your Jellyfin data directory?

TLDR; you have to start over if you don't have a backup. The database has your users and passwords, your watch status, where metadata is located for each library entry.

Very little is not in the DB. Maybe some network and transcoding settings, but not much else.

hey.
Yeah I exited out of the program from the taskbar. And no I don't have a backup of the library.db file. It looks like every time I try to start the program it creates a new library.db.bak#

So how do I go about starting over?
I can still read everything in C:\Users\COSMOS\AppData\Local\jellyfin.
Is there anything that I can save

Delete or rename both of the .db files, jellyfin.db and library.db.
