In the incomplete folder there are two small files .dat and .bak These are often damaged if Limewire crashes, and if they are, your incomplete downloads may not complete. You can stop the downloads in the download window, and possibly try ro restart them one at a time, but I'm afraid it is likely you will have to start again....
This thread might be of help however ... no guarantees
