So you couldn't get game managers to work for you? Also sometimes the mod menus have force host in them just are easy to overlook or not see, try looking in the Host only menu, main mods menu, if not there just look around, n sometimes the Rtm tools can freeze do to outdated or only for certain regions of the game, but havnt heard that from a CoD. If you need help skype me :bmob10189 I may take a lil but to respond as I got a lot of things going on all the time, but I'll help u out as soon as I can.

I got mw3 ultimate tool to work, but my connection is not good enough for host
