It looks like your DB is trying to use Generic combat routine instead of Trinity. On DB main window, goto Settings/Bot and change the "Last Used Routine" to Trinity.
If it doesnt work, I suggest you to delete the entire folder and do fresh installation, then enable Trinity, QuestTools and any other plugins you want to use before starting the bot. On first start, DB will ask you about which Combat Routine to use, there you need to select Trinity
