AutoCAD, now, at least the 2005 version, IS usable, with some hacks and in demo mode. The big remaining problem is the activation page that shows blank.... But the trial version has no limits, besides the 30 days. So, if you have a license, what you can do by now is re-install the demo after the 30 days... I don't think there are legal issues as long as you own a license. Max
