Gnutella Forums - Old Downloads/Incomplete files

My Limewire 4.14 on Mac OS X.4.10 hung yesterday for the first time ("This application is not responding") so I just force quit as when any application hangs.

When I reopened it it told me it "Couldnt load old downloads".

I wasn't overly perturbed as when you accidentally clear unfinished downloads you just go to the Library > Incomplete files menu and Resume the download.

All my half-finsihed downloads being shown in the incomplete folder on Limewire, and also in Home > Incomplete, but when I click Resume to get them back onto the main page, they all reappear at 0% !
Somehow it isn't realising that all these files have already been part downloaded!

Does anyone have any idea how I can make it realise I have already got X% all these incomplete files?

Any advice would be much appreciated. It's taken ages to even get half of some of these downloaded.
Thanks!
