First of all, Wich facetime version is the lastest? My facetime says its 2.0, but Mac AppStore says 1.0.2, is that the version 2.0 ? Or 2.0 comes only with mountain lion? However... the problem is Facetime is not activating, It was working well but I tryed to change my account (I logged of on facetime), then I deactivated. Now I cant find a way to log in, "Activating" its just not working. Any suggestions?
