Just to confirm - the SD card that you are using is FAT32 format, correct?

Can you post the following:

1. The contents of the nng\crash.txt file (assuming it exists)
2. A picture of the root of your SD card
3. A picture of the contents of the "nng" directory
4. The contents of your nng\sys.txt file.

That should give us something to go on.

Also, just to confirm - are you seeing different results now than you did before renaming the "igo8" directory to "nng" and the executable to "nngnavi.exe"?
