I do agree that I have seen enough threads from folks who have not gotten download links and such that I think something is getting goofed up to the point where someone within Cakewalk ought to get it sorted out.
If I can buy stuff from the Dollar Store online, flawlessly, I would expect the Cakewalk store process to simply work. Billing and payment systems have now been around for decades for web purchases.
IF there really is a problem at the Cakewalk end, this would just give ammo to folks who like to pounce and attack, and it leads to all kinds of non-productive noise.
I am hoping this gets fixed for you right away,
Bob Bone
