[amibroker] Free Professional mode trial?

[davhol_03086]

I downloaded the free trial, but it comes up in Standard mode.  I
assume that you can not try the software for free in Professional mode
and there is no refund.  So I have a few questions.  I use IQFeed as
my data provider and Interactive Brokers as my broker.  Will this
combination work?  Is there trading with IB from within AmiBroker or
will I need to trade with an external program (tws)?
Thanks,
