TransDEM Forum

I moved my User data files from TS10 to TS12. All well except that TS12 now shows some UTM tiles (made from TransDem originally) as faulty though not all. In one route (an older one from 3-4 years ago shows correctly, but the tiles in a newer routs show as faulty and do not show in surveyor. These are the warnings in Content Manager 3.7; "Warning: Required tag 'category-class' was missing and has been set to default.
Warning: Required container 'thumbnails' is missing.
Error: The *.texture.txt file is missing for texture resource 'utmkarte (2).texture'." Is there some way of correcting these tiles - about 20 of them?? Can any of you help with this issue? pdw
