YNAB Pro's codebase is retired. Support for YNAB Pro will continue through 2010. We are focusing all of our efforts on YNAB 3 and its movement along the road to software perfection.
I'm also having this problem, I can't seem to import any of the paypal download formats. I'm on a trial of YNAB, and if I can't get this working, I'm not sure about purchasing.
When I try and download paypal, I only get one of the five items to show up. Three of them were purchased on the same day, yet aren't imported. Anyone else figure out a solution?
