Some users are experiencing problems loading Nodiatis with the latest java version.
For a temporary solution for windows users, uninstall all current java versions and install this previous release:

When you log on you will be prompted to choose to update java, you should in this case decline. At this point, continuing to support java seems like it may be more work than it is worth, and we are looking into moving our interface to HTML5.
