PayPal Advanced version update: it would be great if Woo would include a "1-2-3 how to update PayPal Advanced versions instructions" (for dummies) in the docs so that it works seamlessly with woo commerce. There are no instructions on how to update and this doesn't work:
"To update the plugin manually, you should unzip the download and load the files via FTP and just overwrite the existing files, there is no need to deactivate the plugin and no need to delete any files. You can’t manually update WooThemes plugins via your WordPress admin unless you have activated your licenses, you must do it via FTP."

You can't overwrite the existing files.
