Playing partially downloaded files
 

I've been using Limewire for a couple of years now (currently using 2.7.1) and I just upgraded to OS 10.2 yesterday. Up until yesterday, whenever a file was in the process of downloading I was able to double-click it and it would go into iTunes as a preview. Today, nothing. The directories are being shared, the files, once downloaded can be found and put into the list, and iTunes 3 is selected for internet playback, so I'm a bit confused. Also it appears that Limewire wants to send it to iTunes for playback because whenever I double-click the file, the iTunes window moves to the front, but the file doesn't show up (like it has for the past couple of years).

Help, and thank you for any assistance you can give me!
