Hello,
I to ran into this problem today. The reason that I found that the file would not transfer to the shared folder was that despite Limewire not picking up this information before downloading the file, the file is actually a identically named, and sized file that was already in my shared folder. After looking at the T-nu,ber it showed the correct file size that was a duplicate. I just remaed the file and cut and pasted and it transfereed over fine. In order to do this file transfer you have to close out of Limewire first, otherwise you will get a "file in use by another program" message"

Hope this solves everyones problem, and hopefully the techies at limewire can incorporate the code so that the program does a higher level of check before downloading....

Cheers,
The Webman
