For working with 9.5 Item resourcce you are working with a single database table but 2 client RDBs.
Database arcadia.dbo.ItemResource
Client db_item.rdb and db_item.ref
or db_item(ascii).rdb and db_item(ascii).ref if launching ascii
I have not gone there yet but maybe the 9.4 still work with the 9.5 clients but you might be doing something wrong.
