Months ago I found Xbox 360 Profile Editor on the internet compressed with a keygen (the guy who uploaded it had the dev's authorisation). It's a pretty useful program which allow you to lock/unclock achievements for free (unlike Horizon) and it allowed me to lock achievements on games that I wanted to suppress of my profile. The first time I didn't have any problem using the keygen and unlock the full program stuff but it seems my 'license' is of and I need to enter a new one and that's the problem. I use the same step by step method as the last time but when I get a 'The program has ceased to function' message.
Here is a link to the file http://uploaded.to/file/32sflwpw so if you notice something that can help me... Anyway, thanks in advance and have a nice day!
