Radarview: Lost *.out and *.wpt files

Hello,

I've been using FR24 Radarview (Premium) with a long list of .out and .wpt files in Firefox. After switching to another (Chrome based) browser, the .out. and .wpt files don't show up in the Radarview Settings User data menu. I'd like to have them back in the Chrome based browser.

How can I get the .out. and .wpt files back in the new browser?

Thanks for your help.
