Unfortunately, in some cases, depending on the LXBeams version, the option to open the download webpage when notified that an update is available is not working.
This does not mean your license is not valid for the new 5.4.1 version. If you need the link for the download, you can either put your e-mail into the regular download request page (https://www.claudeheintzdesign.com/lx/l ... nload.html) to receive the link.
Or, you can e-mail and request a copy of your license--which will also include the download link.
