I am trying to get KBrizzle's Final Tree Patch to work. I have MW2 installed on the HDD and I have put the patch_mp.ff in the MW2 directory. I tried starting then to find that there were no mods. After research I found that the RSA checks n' stuff have to be removed from the default_mp.xex first before the mods will work. I searched forever and found none available for download with the checks removed. I finally found a program to disable the checks and then replaced the one I had on the Jtag with the cheat enabled one. I then proceeded to play, but the game will not start. it says that "the game cannot start" and that I must "re-download the game". Has anyone found a solution to this problem? I would be grateful as I do not want my jtag to go to waste.
