If you mean that the serial number is invalid (or used up), you can contact Adobe Customer Service, explain the situation and they may reset it for you.
But it's more likely you'll have to re-buy the program. Without a valid serial number, you need to buy a new one -- which essentially means buying the program again.
Are you aware of Adobe's transfer of produce license details?
You need to ask the people from whom the product was purchased lots of questions. If it is a used program, then the original user had to use the redemption code to get a serial number to use the product.
What you need to know from the seller
a. details of the Adobe transfer product license
b. serial number of the product purchased
c. if the seller still has the program activated on his/her computer
(Adobe allows the user to use the purchased serial number on no more than 2 of his/her computers.)
Thanks A.T. Romano, but she bought it from Best Buy, so I have no idea who owned it before.
OK thanks, Steve Grisetti! I'll give them a call and see what I have to do.
I was not aware that Best Buy could-or-would sell used software... you need to ask Best Buy for help with "their" used software
Was this in a store, or online... and if online, was this direct from Best Buy, or does Best Buy have "merchant partners" like Amazon?
Thanks for the reply.
Definitely contact the seller as soon as possible about the details of the transaction.
If no response from a possible online seller and you have a local store for the seller, then visit the store's Customer Service and or Geek Squad.
When I went to Best Buy online and searched for Premiere Elements 11 a page came up that shows that program being sold by "marketplace" vendors

I did not click through to go to any of the vendors, so I don't know if any of them actually sell USED software
She actually bought it in one of the stores before Christmas in their markdowns. This weekend was the first opportunity that I had to download it.
