Upgrade error stops limewire program
 

I have installed the french version of limewire and the first thing that happens when I try o run it is a message saying "Mis à jour vers la version pro" which transaltes as do you want ti migrate tothe pro version, I cannot say yes or no the pop-up has no buttons to press and doesn't react to keystrokes. Does anyone know how I get round this or do I have to install a different version.
