I owned ALL of the algorithms. I did that "MAX" thing where I bought enough to qualify to get ALL of them. As I understand it, when I repurchase an H9 I can download all of them again. Correct?
If you repurchase an H9, you'll be able to download again all the algorithms that you purchased (and the algorithms you got with coupons and so on). So, if you had a standard H9 and you bought 15 algorithms to Max out, then you still have those 15 algorithms in your account (plus your coupon stuff). If you want to have ALL of the algorithms, you'll need to buy a Max. (Considering the fact that you sold a Max, I guess that will leave you breaking even.)
