Unlock All never works

So I have a problem with every single hack out there that includes unlock all, so basically, yes, it unlocks everything, but when I try to use them, it spawns me with no weapon, so I just started this game and I tried equipping the M40A5, and it spawned me with no weapon at all, does this happen to everyone or just me? and is there a fix for it?

It only unlocks the cammo & weapon attachments... not the actual weapons.

To use the new attachment, you must already have the weapon unlocked or it will be invisible..
