THIS THING IS A DREAM (although I did have some kind of issue opening up a file.) I used the MERGE function and it merged some files I didn't need. That was weird. So I'm editing one page at a time instead. That seems to be working.

Great customer service I messed up, and realized after being billed that I hadn't actually finished cancelling my membership. Customer service (Anna) was very helpful, voiding the payment and cancelling my membership, which is a far better policy than most companies have. Her messages were friendly and the response time was very quick.
