it's my friend he said "im sure no body can crack it" so we deside to post it here

They don't know what packer or protector was used or have an idea of the expected level? What's with the "login"?

when u click button the crack me connect to server that check login info, we made it because it's more easy to crack when it's stored in program, it can't encrypt string in runtime.

if you want us to get the valid information then no because we would have to bruteforce what you have on your server which is basically impossible but to crack it

 

its not hard at all
