This morning I went to go load up my backup of killzone and play it online but as soon as I loged in the game sends me a message saying it's disconnected me because I'm using a cheat device, I'm thinking it's because of the ESR background code when using the non-off version? or maybe FMCB boot? or somehow it detected that the dvd isn't the original? Any insight with this would be helpful, COD3 and BF2 both work flawlessly online.

The game also passes the DNAS test, and downloads and installed the update required for the game before he send me the cheating message
