I'm not near a SQL install to verify but I think you need a period between dbo and dnn_NPC_. You may also not need the fishlips ({}). In other words when you do a search/replace for {databaseOwner} replace it with dbo. and for {objectQualifier} replace it with dnn_NPC_

Oops, after re-reading your post I forgot to take out the brackets. Here is an update:

I should check for further replies in the moderation queue before I respond.

So let's take a step back. Did you start over with your upgrade process, from a restore, or did you try to continue working with your broken upgrade?
