Current Mega Unlocker and Trainer for mw3 has been patched in a recent update.
How did I know? I can't apply anymore customization to any of my classes anymore
Not just me but my buddies and everyone else who uses mega unlocker is having the
same problems after the recent update which was yesterday(April 17th, 2012) :/ So any solution? New mega unlockers and trainers maybe?
I want the one where you can put a weapons proficiency on even with two attachments
