Question about... OLD lisence...

Hey there, I was wondering if the old lisence was still posted somewhere.. When I purchased TGE (long time ago, but Im finaly getting going) it used to have a different lisence.. then they came out with a new one.. but it was said you could use the old lisence if you were a current owner when it switched.

Not saying I want to use the old lisence.. I just dont remeber what exactly changed.

Thanks
