thanks jon, that's exactly what I mean.
you cannot move an inch without the serialnumber ... but they can't even tell you where to find or how to get it... and the reaction of the customer service and this forum shows, that there is a serious problem with this process. otherwise there wouldn't be scammers around ... not big enough to fail ...
Serial numbers for PSE start 1057 (24 digits, all numbers, no letters) and are usually found on the disk wrapper inside the box or for downloads, within an email or may be found under your purchase history within your Adobe account.
If you have a redemption code (letters & numbers) sign-in at this link to convert it into a serial number.
