I'm not sure if anyone else has had this problem, and its not exactly an issue in downloading but....

After I begin downloading a file, either while its downloading or even after its done, when I try to click on the file to launch it, nothing will happen. After I try this 3 times limewire will completely close. it is not giving me any error message at all. it just closes completely. I have tried uninstalling Limewire and installing it again, but it still happens. Anyone know what might be causing this??
