You probably haven't installed your new licence since you added the Advanced FTP option to it.
From Common purchasing, upgrading and licensing questions
I paid for the FTP or USB feature but it doesn't work!
Add-on functions are controlled by the program certificate that you install into your copy of Opus. If you added on these features after your licence was issued you should have received a new program certificate via email. This needs to be installed using the Help / Licence Manager command to enable the new features. If you didn't get the new certificate you can retrieve it from the My Account page on the GP Software website.
