Start from a blank screen (press Clear, *not* Refresh), then enable Timer. Within a few seconds, the list of available posts should be retrieved, green = marked for import, red = will not be imported.
Do you see anything at all at this point? If the answer is "yes, I see some entries highlighted in green, but nothing is being imported to the queue," then just wait a while. Alt.binz imports NZBs from RSS in 60 second intervals.
If "no" ... please be specific about what you're not seeing.
