It should be actually D317400.db and D2925050A.G2S files. Try also rename all other maps except NTU Europe one (not just disable maps in UI, but rename *.img files to something like *.bak).
Tried that today, too. After renaming all other maps and reboot I was left with
CN EU NTU 2012.40
CN EU DEM
CN EU NTU 2012.40 3D
So, still no Traffic trends for EU. So frustrating
