How I can use urlread to read a .dat file from a 'real-time' web source

I am trying to use urlread to read the information contained here (raw data updated every hour):

http://xweb.geos.ed.ac.uk/~weather/jcmb_ws/CR10X1.DAT

This is weather information which is comma separated. I require it to draw a sun path diagram for a solar project.

I have tried the following prompt:

str = urlread('http://xweb.geos.ed.ac.uk/~weather/jcmb_ws/CR10X1.DAT');

But I get the following error:

??? Error using ==> urlread at 111 Error downloading URL. Your network connection may be down or your proxy settings improperly configured.

I have heard this can be a security issue however the same web page stores past data per month as csv's and those files read fine:

http://xweb.geos.ed.ac.uk/~weather/jcmb_ws/JCMB_2013_Feb.csv

Eventually I would like to store this data as a matrix so that it can be accessed/continually updated with the new weather info.

Thanks in advance.
