disaster in Spain.....

Hi everyone,
im in urgent need of assistance, im running a tour of Spain on motorcycles and my maps have gone pete tong. have the latest Basecamp and the latest updates tp the city nav 2019..3 on bpth BMW navigator 6. my maps and routes were absolutely fine in october when I planned and ran all the routes. 3 days ago I updated all the software prior to setting off and all the maps went crazy. I have deleted them off the satnav and reloaded them several times, the basic routes are there but all the waypoints have disappeared from the maps themselves. they are in favourites if looked for but do not alert as part of the route. im struggling to get round each day as the coffee stops and drone places are now coming from memory. any thoughts?
