Sometimes when I'm downloading a file and it's going slowly or not finding any available hosts, I'll cancel the download, search again, and try to download again.

However, sometimes when I do this the program refuses to try to download that file again, complaining that I'm still downloading it even after I've killed it.

What can I do?

(I'm using v2.44)

That's a bug, but there is a simple solution: Don't cancel downloads you want to continue. Manually research for the file you want to have, instead, since any new hosts LimeWire finds while performing a search for a file, will be added automatically to the existing downloads.

Yes, the same thing happened to me yesterday. You can do what Taliban wrote or you can close LimeWire and open it again (but you will lose all your stable connections).

Canceling a download and exiting the application and restarting it from scratch will keep these ghost file in the download set. I surmissed there is a small bug in the download.dat update code.

Nope, that's probably not it. I guess it's related to the GUI. Restart LimeWire, kill the download and restart LimeWire again. That should work...
