I don't mean to be rude, but why can't you people actually PAY for the software that you want to use and SUPPORT its continuing developement. I'll admit that a lot of us have "downloaded" things questionably, but a thousand dollar software really crosses the line... And posting it on a public forum; not too smart.
Just because it's an older version doesn't mean it's worthless. Why don't you call the AutoCad and ask for a price quote on their older versions; it's not going to be free.
