Is it no matter how big the file is? Coz I sometimes get this when trying to dowload large files, I haven't really been able to see any consistency in it :o/ A good thing to do is to make sure your TEMP folder is empty, it can cause all sorts of weird problems if too many .tmp files are in that. Don't know if it solves THIS problem though.
