Okay a friend of mine is a mac user, and i do not know anything about macs, i was tryiing to get adobe cs5 for her, it told me to use the trial then open after effects, i could not find after effects, so i tried using another program also to edit the host and put in the trial but it keeps on saying trial is going on, and that the key is invalid, is there a way to change the preferences so i can restart the adobe trial so i can put it in. i need help greatly, and if this is not the forum to go to PLEASE direct me to one to go to. this is important i only have one day to fix it.
