Available from now on you can download AutoCAD 2009. Download is free as one would expect and you can use it without limitations for 30 days. But there is a bad restriction. This offer is valid only in the United States and Canada. You must be located in these countries to be able to download as your IP number is controlled. Trying to download from Sweden I got this error:
Location Error - Trial Download Request
Trial Not Available
This trial program is not available in some countries.
I think it should be available to download more freely.
