Decoding problems need help

Can any help me out. I cant figure out why Xnews wont let me decode
anything. iI select the files i want to decode then Q them up and its says
they're decoding. But when its finished it tells me 0 files have been
decoded and when i look in the file where i sne all of my xnews downloads
and none of them are downloaded. So if anyone can givwe me any help that
would be apreciated very much. Thanks in advance
