To download lenses go to your Dashboard: https://www.squidoo.com/lensmaster/dashboard and click the link that says “download all your lens content for this account” so you have a backup, because all content on Squidoo goes away in October. You can read more about this in the FAQ’s.
Once downloaded you should open the XML file with a text editor. All computers should have a text editor program installed.
We’ve have resolved a lot of the bugs associated with downloading content so you should be able to get your files now. If you are still having problems please do file a detailed bug report.
