@ GCS
I cant recall the issue I had but I did two things.
Uninstalled BK - never play the thing lol
With MW4 installed I restarted the install process with the CD and basically did a repair (re-installed without un-installing)
This refreshed the files and got rid of some of the custom user made add-ons I had HUD patch, no-cd patch from v2...
Then I installed the softbread patch from the link I posted which according to softbread is now at a new location:

GL and let me know if that works.
BTW BK uses a different version of the macrovision product so its either that or add-ons you have that are causing your problems (my guess)
I hope this thing works with the next mech pac so I can use all the bk weapons plus the new stuff in reg MW4
