Q u o t e:
You should be able to continue leveling and training your professions immediately after upgrading, but the rest of the trial restrictions will remain in place for up to 72 hours to prevent possible fraud. Keep in mind that this only applies when upgrading online—choosing to upgrade by purchasing a boxed copy of the game removes the trial restrictions almost immediately.
The triple experience should apply from the moment you have linked your account with the Recruit-A-Friend promotion, though; it is in no way connected to the fact that you are still restricted by the trial status. What level are you and your friend? Check your Combat Log and see if the following line is present after killing a monster:
"Player gains 'X' experience ('Y' exp Refer-A-Friend bonus)"
