VoipDiscount free trial not working?

Hi and Happy the New Year

I tried today for the first time
the free trial call at voipdiscount.com
but is not working

Although I try to call to destinations
like Australia or Canada that are
in the "free list" I keep getting back
the message:

"Sorry, this destination is not free.
Please buy credit or log in.
Or call only the free destinations."

Any clues?
Is this "free trial" not available any more?

Thanks
