I bought CS5 master collection for windows off ebay, he has the trail boxed version and the email with serial number full version serial from adobe. I got it cheap I wouldn't have bought it if ebay didn't have buyer protection (if it's fake I can get my money including shipping back). when I get it how to I verfiy the serial is a legitamate one, that can be upgraded and is issued by adobe, instead of a generated one?
You can call Adobe customer service, provide them the serial number, and they will be able to tell you
if it is legit
Ok Thank You!
