Thanks for your reply LOTR.
Yes have seen alot of posts from folk such as yourself on this and have noted the typical fake files (have had experience of the 5611 Kb one on other occasions but not recently).
Just to clarify a few points. Really have deleted ALL files/folders related to Limewire and tried to start with a clean slate. Hasn't worked. Should also point out that I've had this problem trying to download many different audio files. So it's not a case of me trying to get the same file. Any file I now try to download seems to give me this issue. If I delete the downloads.dat it creates a new one, but the problem persists.
I had tried before, but just retried your advice of shreding the Incomplete folder, then recreating it. Even then, starting with the new empty Incompletes folder, whatever I try to download, I get the issue.
Another point that might be relevant (but could be coincidence) in recent files I've downloaded, while I've been able to play files using WMP once completed, I don't know that I have been able to play them during downloading with the limewire player. I do recall warnings about "unplayable files". Just to experiment, I just downloaded a file, which I can play using WMP, but leaving it in the Saved Files folder, can't launch from within LW using the LW player...that's weird eh?
Not too sure where to go from here.
