Hi All,

I am having issues with the quandl api. I have set it up per the instructions.

 data = Quandl.get('NASDAQOMX/OMXS30', 'start_date', '2012-01-02', 'end_date', '2014-01-02', 'type', 'data', ...
                        'api_key',apikey); 
logReturns = 100 * diff(log(flipud(data(:, 2))));
noObservations = length(logReturns);
Response stream is undefined
 below is a Java Error dump (truncated):
