SABnzbd Forums

I've used SABnzbd for a couple years without problem. My friend set it up for me but I have next to no understanding of how it works and it hasn't been working for me lately. When I upload a new nzb, it says it's downloading at 0 or 1kB's and then after about a minute the download fails. My friend suggested it might be a problem with my payment, but I just got an email a few days ago saying my annual usenet payment was successful. Does anyone have any ideas what I can do?

What does the download reports say? (Click on an item in History).
If there are a lot missing articles, then the post was probably removed due to a DMCA takedown request.
