I have bought 2 Memory Map 1:25,000 maps version 4 and also several version 5 ones. All of these load up and can be viewed in Touratech QV3 (3.0.1.35) except for one of the titles which has four .qct files, none of which will open in QV3. I just get a message saying "MAPS openmap: Error opening bitmap c:...\...\thefile.qct. Why is it that they all open except these, when some of the ones which open are the same versions?
