If ca closes when you open mhs, i think thats because ur bypass is not good enough?
If u get a hack from a site mpgh .net, fps.com, ***********.net, the hacks include a bypass.
run combat arms, before u open MHS goto ur CA folder, open the Hshield folder move everything in the folder to a new location, then open mhs. but there are 3 files u cant move cuz they r being used:3n.mhe, v3warpds.v3d and v3warpns.v3d
Hope this helps
