Gears of War PC Achievements Not Unlocking

Hi, I need some help on how I can get my achievements unlocked on GOW1 for PC.
I have the Razor copy which I managed to get working today, however I have to play the game offline with my Gamertag logged in (offline). Whenever I got the requirements for an achievement during the game a message pops up saying “when you next sign-in to windows live the achievement will unlock”.
So I logged into my account playing Tinker this time online and I thought my achievements would unlock however they haven’t. Achievements usually unclock for windows live PC when your offline and then when you log in online your Gamerscore gets updated
Does anybody know of a solution to unlocking achievements on a cracked copy of Gears as many of you might know that getting at least 1 achievement on Gears1 PC unlocks a chrome skin in Gears 3.
Many Thanks

No that’s not true, other games I’ve played cracked like Bulletstorm, Tron Evolution, Bioshock 2 and Fallout 3 etc all updated to my online xbox 360 gamerscore.
I think you might have to delete a file that stops the game from blocking your achievements from unlocking…

SOLVED IT – LONG A TEDIOUS PROCESS THOUGH
Answer #4
I’d like to know how because some of the Gears 3 unlocks are via Gears(1) PC Achievements.
Care to elaborate on how you managed to get the Asscreaments to register to your Live Gaymore tag?
