Every File Downloaded with CRC Error and always short some blocks

[zebra100]

I tried your Sabnzbd for several files. I like the speed and easy to use, but every file I tried to download ended up in CRC error with all null files and par2 in the completed download folder.  SAB never unpack a complete file right and I knew the source files are all good, because other people did well. I repeat to download all or part of the files again for days with same results.  I used  Quickpar to repair and relocate the missing par2 files, always ending short some blocks.  I used Niouz to download same file without any null file and all rar files and unpack successfullly but i don't like the slow speed ans response of it.  What is wrong with Sab, is that my antivirus of switch in Sab messed it up?  I will try to turn off al switches in Sab to see.  It always ended up in failed folder with some rar files missing and a bunch of null files and useless par2 file.  I used quickpar to add all the files (null, rar, par2 ) and create new par2 files and click all of them, it still missing some blocks.  I just don't understand.

SABnzbd will log warnings and errors for effective troubleshooting.

Did you try to download these files with another client (grabit maybe) ?
Does it download then ?

What pay-server are you using , please check if they are all 100% on your pay-server
Other people may have a retention of 300 days & you only say like 150 , and then you can also have problems that it is not 100% complete anymore on the server if it is a bit old
