I highly doubt you updated the lines and names, my bet is you saved the new .swf, put it into the 19.3 mod selector and tried to make a client, correct?
Well theres you're problem right there, +1 to you though, for not being like 90% of this section and actually trying shit yourself and not just leeching or posting "fre hax pls, hak no wurk no more update pls"..
Anyway wait till Cry or some other poor soul updates the mod selector, I only partly update the selector for my own shit I use, so thats no good as a real release.
