Trust me it works. Try changing computers and download it again on the computer or laptop or whatever you have. The reason why it doesnt work in some computers is because of anti-virus programs. Although, the score sender is not a virus, the computer blocks the program from turning on. Its not the computers or score senders fault. The fault lies on the anti-virus software itself which you cant do anything about.
