Merlin started off well but is no longer usable. Everytime I try use it the response is that I've used all my credits and I need to Upgrade to Pro. The problem is that I haven't used it for a long time so there should be plenty of credits. Contacting Support was unhelpful saying that I needed to wait for my credits to reset each month, but after a few months of not being able to use it I'm fed up with the software and Merlin support. I would refund if I could.
