Garmin Express has uninstalled Basecamp and will not install new map on device!

I have run the new Express to update my Lifetime Europe map and not only has it removed Basecamp from my Windows 7 PC but refuses to load/update on the Nuvi775t. It has downloaded to the PC but I want it on my device as well. The error Express is saying is 'insufficient space on device' This may be so ( 1gb left) but in the past the Lifetime Updater has removed the old map and installed the new one automatically. I do not want to use an SD card.

How do I now go about putting the map on both device and PC?
