If you are seeing this message it means your template is not up to date. Note: If you have a template from before ArticleLive NX 1.7 you will not be able to use it in the new version at all. You'll need to select one of the new template.
If you haven't made modifications to your template...
To update your template to work with NX 2.0, go to the 'Templates' section in your control panel and select your template. Then at the top where it shows you your current template, click 'Check New Version'. It should tell you there is a newer version available. The button you just clicked should have turned into a 'Download New Template' button, click that and your template will be updated to the new version.
If you have made modifications to your template...
You have two options for this. You could rename your current template folder to something different e.g. 'Default_backup', then download the new version of the template through the 'Download Templates' tab on the 'Templates' page on your control panel and just remake your old changes to the new template. Or you could follow the template upgrade guide located in the zip file: /docs/template_changes.txt
