Trying to update treb's client, tutorials are incomplete

I'm computer literate and can hold my own for most tasks, but this shit is killing me. I found a tutorial on here using FlashDevelop, JPEXS and WinMerge, but it seems to be incomplete and skips lots of steps. There has to be an easier way to do this? Or at least somebody could explain better how to do it with these programs. I've fallen in love with Treb's Client but it looks as if elisrael has given up on it, so I'm hoping to take over the duty of updating it. (if it matters I can somewhat code in C#)

he hasn't given up on it and he's porting all his shit into my source and we're releasing and working on it together, the crazyclient available right now is a hotfix and will be updated later on with all trebs work as well as mine.

and no, there really isn't an easier way, it's honestly a bitch and a half and tedious as all hell to get a working source
