Many databases that do not have the "direct export" button can still be used to download references into EndNote.
To do this they require you to save the references to your computer desktop and then import those references into EndNote by using a "filter file".
To see basic instructions on how to download your references to your EndNote library:
In order to download a file to use in EndNote, you must open the file in the EndNote program and allow EndNote to save it to the directory it creates for that file. If you allow EndNote to do this, the files you download: Filters, Connections or Styles, will appear in the appropriate Manager.
If we could just say one thing...
Back up your library!
Don't lose your work, make sure you regularly save a back-up copy of your EndNote library somewhere safe.
And don't save your "real" copy of your EndNote library on cloud storage (Dropbox, iCloud, OneDrive, etc), because the files are more likely to become corrupted. It's much safer to save your library to a hard drive.
