I am having a similar problem.

I am running Limewire 1.7 with OS 8.1. When I download files identified by Limewire as MP3s I cannot play them. When I get info on the downloaded file it is simply identified as a Limewire document.

I hope someone can post a solution to this problem or at least an acknowledgement that it is being corrected.

If you get any info please e-mail me at limeware@littig.com

Thanks
