Downloaded files are neither saved in library nor in incomplete folder
 

When I'm using limewire on my Mac (Mac OS X), downloaded files are neither saved in the library nor in the incomplete folder. I cannot locate these files anywhere. I don't have this problem with the limewire version I am using on my PC. I have tried to change the folder where downloads are saved and it worked for a couple of downloads but then the problem occured again. Is there any way to locate these downloads or to make sure downloads are saved in the defined folder?
