Hi Chris, tried as per your instructions though still having problems, the programme just stops and in the DOS Box it still reads:
Where it writes the progress of the files and where the DOS error comes up it reads from Step 2 Building Mesh for Tile +53-001 :
Loading of elevation data.
No elevation file found, I download it from viewfinderpanorama (J. do Ferrant)
i) Done. The zip archive will now be extracted in the Elevation_data dir.
i) Done. The zip archive will now be extracted in the Elevation_data dir.
Then nothing happens, that is when I went to the DOS Screen and saw the message:
FileNotFoundError [Errno 2] No such file or directory ..\\tmp\\N30.zip.
I incidentally had a look in the Ortho4XP folder and did not see a folder named Elevation_data, so put one in but still came back with the above messages.
I even tried an earlier version of Orth4XP and that also gives me problems and will not load certain files. Just don't understand why this does not work when others seem to have no problems.
Maybe as a last resort you could give me a link to where you downloaded Ortho4XP and see if that link is any better Chris, many thanks on advance.
Sorry Nigel, I can't help with the Ortho business, but I will be very interested in how you get on.
I'm not!!

still looking for reasons why this is not working but pleased to hear that you have now found a solution to your weather problems and wish you many enjoyable flights.
Regards
Nigel.
