Problem with subtlexus reader

[lyambailey]

When using the subtlexus (reader) function to load in the following corpus: SUBTLEXusfrequencyabove1.xls (obtained from here: http://crr.ugent.be/programs-data/subtitle-frequencies), I get the following error:

subtlexus('SUBTLEXusfrequencyabove1.xls', fields='orthography')
