Hello...my first post !

When I download .sit files, sometimes they are called a "Limewire document"in the download folder and I cant unstuff them or do anything with them.

In the Limewire library, however, they are displayed as.sit files. (No problems with mp3s.)

Does anyone know what the problem is here?
I've read the FAQ.
Limewire 2.9.8
Mac OS 9.2.1
No firewalls,etc.

Thanks for your help!!!
