Do you experience problems during downloading?
Check your connection in Status and Interface settings window.
Use Test Server in Config > Servers.
We will probably ask you to do a test using only basic settings.
Do you experience problems during repair or unpacking?
Enable +Debug logging in the Status and Interface settings window and share the relevant parts of the log here using [ code ] sections.
I have a problem that just started recently: when I try to download things using the "http offer" in NZB TV or by clicking the little "SAB" icon that the nzbdStatus extension adds to newzbin listings, the file gets stuck in SAB (0.4.5) saying "fetching msgid ####### from www.newzbin.com" and never actually downloads. If I manually download the NZB file and put in blackhole directory, it downloads fine.
