Need A little Help with hex editor for Bypass

Ok i have the "new" bypass that came out and i made my own copy and it does not work very well it d/cs after 5-10 mins in game, i made the file right just like lolz2muchs tutorial said to do accept one part,

#2 open up the old engine.exe and change the version number to match the new engine.exe that came out after the patch

I did not do that part of the tutorial and i dont know how too. But im sure that its not my "programing" skills ( i say programing, but its not realy) because i downloaded someone elses version of the bypass and it did the same exact thing. "connection to server has ended"

so i dont know if the lack of hex editing is to blame or it doesnt work for me, btw im using the unnamed fly hack 1.2.1

i tryed running capatiblty mode and still no results, i have windows xp


Well thanks for taking the time to read this and trying to help me solve this because i cant change the version number
