User reported that alt.binz could download files that Newsbin couldn't. He provided some NZB's to try. I fed one into Newsbin and all the blocks went red and the logging tab showed "430" errors. I then installed and fired up alt.binz and tried the same NZB.

2 - Found the logging tab and it reported

So, it wasn't really able to download files that Newsbin couldn't. It just looked like it was downloading.
