Photoshop Elements 10 online installation

I tried to download the trial version and enter my serial number when

prompted, but it gave me a warning that the serial number is not valid for

this product. I then followed through on the download of the trial version

only to realize that it is Photoshop Elements 11 (not version 10 which is

what I own). I tried to access customer service but chats were closed and

I was on hold for 38 minutes before being disconnected - additionally I

read that I would be charged $39 for phone customer service; basically $1

for every minute that I was on hold.....in today's day in age I cannot

fathom how a company could even consider charging a customer to support a

product that they have already spent good money to purchase - but thats

another topic.

How can I download a trial version of Adobe Photoshop Elements 10? Every

effort that I've made only allows me to Download version 11 (which I'm

assuming is not recognizing my serial number)?
