I'm unable to register the trial of PD 5.0, latest build, after activating with trial key in email, the registration under Help, is greyed out.... I thought that it might have already been done.. So I logged into my account, under Registered Products, its not listed... So I decided to copy and paste activation key in the suppled field..... How long does it take to show up, as all I could see were all my previous 4.x, 3.x ones. I began thinking it can't be that only full versions can be registered, but i have trial keys on 3.x and 4.x that ARE listed.
