Hmmm, sorry that this is dragging on everyone, now that I have the files in the right place (;)) the tables are being picked up. However, when I open the tables, there are twice as many rows in the table than in the CSV file. And every value in every row/column is NULL.

I should say that my CSV files are actually TAB separated. However, I've tried replacing the tabs with commas and although I then get the correct number of columns, I'm still getting all NULLs. Not sure if it makes any difference, but I've got tons of columns (>50)...
