You have 2 parts to the patch right? You install the 5.77 first, then open the game updater menu. Find where you put the folder called CORE (unpack first, I stick em on desktop to find it easy), open core folder and find the .addpack file. Click on it, wait for the clock thingie to go away. Hit save and play. Your good to go. If your running win7 64 bit with sabow installed into programs x86 you may or may not have problems. Easy fix if you do. Just copy paste the whole folder out of x86 and put it elsewhere. I have mine under C: Graviteam.
