I have a big bad problem. I've been downloading a file for now ±20 hours and then I had to force-quit Limewire because it was slowing my computer as f***. Now it looks like it didn't save my file in the incomplete part. It does lie in the "incomplete ƒ" but when I go to the library tab of limeWire and press "resume", it'll start a new download instead of continuing mine and guess what! I don't want to download those 500Mb again, so please, find a way to get me outta this s***.

Well force quitting LimeWire usually is not a good idea and in your case I assume you have to redownload.

That's what I started doing, ugh, it sux...
fortunately I do have a fast connection that doesn't cost "per hour"

force quitting goes wrong when using limewire in ~1% of the cases, because you could force quit while the downloads.dat is written.

By the way how long have you been running LimeWire before it started using all your resources? I've had similar problems, when I was running it several days without restart.
