You downlded a windows program! It's incompatible with mac. Any file that has a .exe extension can only be run on windows. Did you buy LW pro & get a movie pack? LW pro offers no such thing. The real LW pro can be obtained here: http://www.limewire.com/english/content/download.shtml

Perhaps you should see this: http://www.gnutellaforums.com/showth...5&pagenumber=1
I'd suggest you cancel the transaction & get your money back if you didn't get LW Pro from the official site (else you'll probably find you paid for the free version.)

Besides, codecs for windows can be obtained for free if you go to the right sites.

If you want a mac program to view videos then get VLC: http://www.videolan.org/vlc/ (choose nearest mirror site) http://www.videolan.org/vlc/features.html
Unless you want to install upteen lots of codecs or plug-ins for QuickTime player. Some of these are free.
