Keep Getting This Error?
To fix this issue you must change your MAC address before you swap your CID.
Changing MAC Address:
Install SEN Enabler (CEX)
Find it online
You will have text files for console id, playstation id, and MAC address. Don't change anything on them but the actual id/address or you will not be able to change any of them. Easy way to change MAC address is to just change last 2 characters and nothing else. First one to F and second one to any number you desire.
Changing MAC address (DEX):
Change Your Mac Address On DEX [Sticks] (has all downloads) *all credits to -Superman*
*DONT COMPLAIN IF YOU USE THE SAME CID YOU GOT BANNED ON OR PUBLIC ONE, I ALREADY TOLD YOU NOT TO DO THAT*
I'm trying to be general helping out with this as discussion of CIDs are not allowed and will result in consequences. This is just a direction on how to get online on ghosts as many people don't know yet.
