Hi Netcop,
It seems the program is expecting headers in your file. It is crucial that the headers are not moved to other cells, i.e. The first column must be in cell A1, second column in B1 etc...
I see you state that you did not edit anything, so I am just poking around a bit to understand you scenario...
Did you use Excel top open the routes xlsx file?
Does it display correctly?
Perhaps the program did not finish extracting first?
If it is possible, perhaps you can send me your routes xlsx file, or at least a portion of it, say the first 100 lines. Perhaps I can try and see whats happening.
Craig.
