Rosa_Parkadobe premiere. you can just make fake emails so you can get infinite free trials.
no you cant unless you modify your registry
the nice thing about cc is that it is cloud based - therefore you can pay a very small monthly rate for the whole package
if you are only using for personal use and never intend to make any money off of your work surf youtube for some "free options"
if you do ever intend to make money off your work - filming weddings etc(or want a sponsor of a skier you filmed to post your edit) you need to actually own the lisense - therefore you have to pay for it
