The records in Download.dat and download.bak show what you have previously downloaded. If you have deleted that file the records in download.dat don't always change.
So don't worry about it just click on the "continue anyway" option and don't worry about it. If you have'nt got the file already saved in your download folder the new download will work fine.

I am having the same problem, exept the file named is completyly different the the DL and if I continue, it comes in under the correct name but then dissapears
example: if i down load clutch-earthworm.mp3 it says (aproximatley)"exact same file exists as limewire/downloads/shared***** me- backstreet boys.mp3 continue anyways?" ?!?!?!?!? and when clicked on, it flips to iTunes but with nothing selected
HEEEEELLLLLLPPPP me please

CCleaner - Home

Download it.
Install it.
Run it.

Probably fix the one prob and many others.

CCleaner (formerly known as C r a p Cleaner) is free and completely safe.
(But, they won't be against any 'contributions !!!)

Anyway, you'll learn to love it sometime between about 60 seconds to 1 week !

thanks for the quick reply. I guess i never mentioned I'm running a mac but your suggestion gave me an idea: i've dug around a little further and have tried a few other things but I don't think the problems been fixed.
