I see that you have 'Set wrdApp = Nothing', but I don't see where you've terminated the wrdApp session (i.e. wrdApp.Quit). Not having that means you'll have an orphaned Word session floating around.
Hint: Since it seems you want your Word session to be running for multiple documents, you should start the Session independently of all the looping that opens the documents, then kill it once all the processing has been done. See, for example:
