Cheers guys I thought as much, i'll break it to him gently that it's gone for good.
It's going to be very hard for any person losing his Bitcoin because he lost his private key especially if the amount is huge and if you are living in a third would country you know every satoshi is worth the amount in your local currency, so guys be sure to keep your private key in a safe place and make a copy for yourself only.
well, I've also lost bitcoin because of private keys. believe me, i have also done everything, but that doesn't bring good results. Well, what needs to be done when losing is to be patient and go back to searching for bitcoin.
