LAUNCH worked yesterday, what happened??
 

Hi, I'm new.
I've been using Limewire a while, but launch doesn't work any more, and I don't know why. Any suggestions?
I have a mac OsX

Use the explore button to go to the download folder, and single-click on the file you want to launch.

Then, use cmd-i to Get Info on the file, and set the "Open with" option to the desired application.

If the file won't open, maybe it's one of those fake files. You can look at the size to get an idea if it's reasonable.
