I just wiped my macbook pro harddrive and upgraded to Lion OSX. I bought the CS5 Design Premium last year (in a case). Unfortunately, my discs are unavailable, but I do have the correct serial number. When I downloaded the CS5.5 Design premium trial (to plug in my serial number), it says it isn't valid. Is there a place that I can download the CS5 Design Premium Suite so that my serial number will work? Help! I'm a photographer and I need PS to work immediately!
