Does anyone know if I can disable or remove this pack>
You have to remove it from your HDD, that should do the trick.
Maybe he can't find the regular Playlists... :\
Yeah just delete it, you can always download it again if you wish. You can also put it on a thumbdrive.
thats what i do..i have both packs on a usb drive..im i am feeling like original maps remove the drive
If you play using only the regular maps and not First Strike/Escalation, then you play against other players who do not have those installed.. so you'll be playing against more new players and be getting better K/D ratios and stuff like that :P
just delete the map pack of your HDD, you will always be able to re-download if you change your mind provided its still on the marketplace.
