it's a Finder problem--you can try using the PC Exchage Control Panel to "map" the file to the proper app, or just dragging it onto the application you think should open it.

Also, search the Mac Support Forum for "limewire documents" to find lots more about the problems of getting internet files onto OS 8-9

Here's a sample Specific Question re: Documents that will download but won't launch on a MAC.. Help

cheers

btw--that's the trouble with Macs--those old machines just keep on working so looooooong!
