    Serial number invalid


      I have purchased a new laptop and downloaded PS5 (I have previously purchased CS5). However once installed, I get the error message that this serial number is invalid. Worse, I can't use it as a trial version because as soon as I opened it it reset the trial period to expired. Help - I am heading away on a job in a couple of days ...
