my 30 days trial run out..
is it possible to download it again?
Answers: Yes it is possible to download it again but you want to know how to re use it on one and the same apparatus since it is solitary a trial journal, besides if you close to it so much why don't you BUY IT?
If your a student next to no money use GIMP its free.
No, not reasonably anyways.
Try a organized semi-legal trick approaching this: use system restore and restore it to a time since you installed CS3. Now you can download it again. :)
