IQfeed undefined function or variable problem

Hello,

I have downloaded and installed IQfeed correctly, it is working.

Connection to iqfeed through MATLAB also works;

q = iqf('username', 'password')

However when I try to fetch data for a stock etc, it fails:

history(q,'GOOG',5)

IQFeedHistoryData

Undefined function or variable 'IQFeedHistoryData'.

What might be going wrong??

I would appreciate your help.
