i downloaded limewire pro 4.14.10 about a month ago, worked fine till yesterday, when i went to open limewire using desktop shortcut a small black box appeared whick copies everything i do with my mouse.

i have tried to open limewire by pressing 'start' 'programs' 'limewire' but no good, i have also went into program files and clicked onto limewire but no files appear.

how can i get it to work again
