On SE 2d free I have been getting a "Demo" watermark in the lower left area of the page when I print. I understand the value of this software, offered for free, but that would ruin any hope of me using it. Perhaps it's only on the sample page block/border/frame that automatically appears in the sheet view...?
there was an issue with the license at ont point that was causing the watermark. This should be resolved. All you need to do is to go back to the free2d web site and register as an existing user ao get a license update. On the download page, click on the proper link to download the most recent license. The download is a zip file. the zip file will contain a license and a readme. The readme will explain how to apply the license.
