Thank you for your question.
The RadRibbonBar version that can be downloaded from the Registration Benefits portal should be a fully-functional royalty free version - it is not a trial version. I just checked the site (https://connect.microsoft.com/downloads/downloads.aspx?SiteID=40) to make sure that everything is ok.
Please, check your registration page again and let me know if indeed it says that you are downloading a trial version. If so, please, send me the link and the text you see so that we can check the reason for this.
All the best,
the Telerik team
