Have you joined and logged in to RWGPS? The free versions do change from time to time but I have just checked my version and I can still export to my laptop for free OK.
At the moment I normally use the free version of
www.alltrails.com (was
GPSies) to create the course and add to my old
Garmin 810 via usb. The user experience is very similar to
www.ridewithgps.com, but with the added bonus that you can add your own notes in the form of a 'waypoint'; like 'café', 'bikeshop', a feature that is no longer free with
ridewithgps; hence my switch to A
lltrails. One handy feature I like is you can toggle between 'hiking-cycling-driving' when creating, so you can switch to 'hiking' if you want to take a shortcut over a footbridge for example then back to driving if you want to stay on roads. There are two cycle focused modes, '
Bike touring' may include a smooth trail where as
'Road biking' will be on paved roads and paths that support bicycle access.
