Well make sure you are already on DEX then go to Settings/Debug Settings in your XMB and set your Network settings for Debug to Single Settings... Make sure your Environment NP is set to NP. Install the ProDG target manager, put your Ps3tmapi.dll files in the same folder as your RTE tools which you can find in Program files/SN Systems/PS3/bin and you should be good to go... Also before you sign in on DEX make sure you go to Rebug Toolbox and scroll all the way to the right and all the way to the bottom and switch it to CEX x84 or whatever it says... Not sure if this is what you meant but I just figured Id try and give some help in case this is what it is...
