All of the problems are similar the ones we had and we had to adapt the CSV generated by the form software we use to collect data (machform) and even then we have to import data in small amounts.
It was a nightmare experience and one I hope to never have to go through again. And, the worst part was it cost us a lot of time worth more than the price of the product!
On the face of it, without having put version 4 through its paces yet, it does seem to be a better interface than previously but I do hope the improvements are not just cosmetic because WPAI was by far the buggiest and most costly premium plugin we purchased.
p.s. even expert WP developers we know had trouble with it!
