In 2.3 version we separated two different license types of My Remote Files (up and more than 20 user accounts) into two products. They are practically the same except some differences implied by previous license types. Thus,
My Remote Files with more than 20 user accounts is transformed into Remote Files SE software. It has no limit in user accounts and supports remote administration option as supposed by this license kind. Any previous license that allowed more than 20 accounts is supported by Remote Files SE.
My Remote Files with up to 20 user accounts is available under old name My Remote Files. It supports both previous license types.
Update to corresponding product according to your license does not require any additional fees.
