How can I use the downloaded Data Field widget?

Hi mates, I recently acquired my FR245 and downloaded a couple of data fields (apps, widgets?) and tried to select them to use minutes ago with no luck. My question is: How can I access them data field (app or widgets) in order to use one of them on tonights run?

btw I don't have access to my PC until after the run when I arrive home.

Thanks in advance.
