I've bought several items that are dynamic in the past as well, and only just found out that the reason they didn't work in Dax was because they're Dynamic. There's no manual for new users that says "this is what works here and/or there" and we pretty much have to learn by mistake, with apparently no forgiveness involved. I'm not asking for refunds on old purchases - but as I just bought this item I didn't think it'd be a problem to get a refund. If you buy the wrong software in a store, they usually let you return it or swap it. I especially didn't expect the sneering "Too bad so sad" attitude from the vendor. I spend a lot of money here so I thought there could be some leeway. It seems a very poor policy.
