I have exported a list of 2d coordinates as a `List`:

    Export["F:\\coordinates.dat", coordinates, "List"];

You can access the data here: http://pastebin.com/wFSt9DiD

Now I would like to read the coordinates back with:

    coordinates = Import["F:\\coordinates.dat", "List"];

So far this works.

But, when I want to plot the data with `ListPlot` the plot is empty.

When I try `Flatten[coordinates]`, the coordinates remains unchanged.

It seems that the imported data is imported as a text list.

How can I access the data in the list?
