Mark, we're checking right now why the files cannot be downloaded, they will be there eventually!
Update: it seems some data files need revising, including some that you have purchased. Can I offer you a replacement in the form of other markets? You can choose from the event tree, add them to cart and click "Buy", then on the payment page press "Pay by PayPal", but do NOT make the actual payment. I will see your choice in our database and will make a replacement with existing data files.
You have two meetings to replace.
