Right-click on the file choose "properties", click "Actions", and choose "Forget current verification status and reverify." I think that was the common cure for this, but I haven't seen this for a while so I might remember wrong. So it might be one of the next two options or some combination of the three actions. None of the three causes any serious damage (although you might lose a small part of what you have already downloaded), so feel free to experiment. You might also want to check that there really are complete sources for the file, sometimes all the sources for the file are missing the same small piece (if nobody has it, nobody can download it), and there is obviously nothing Shareaza can do about that. Although sometimes using another network can help.
Which network are you using?
