Stupid, stupid, stupid me ! Today, I sent an email to my TAG dealer to order the DPIIx option. I gave him the serial number and the ID of my unit which were saved on my handeld. A few hours later, he replied to me the activation code. Back home, I jumped on my remote to enter the code and found that the ID had changed because of the upgrade from "sp" to "dp" ! I hope I won't have to pay a second time with the correct ID as I have no proof the first ID I gave wasn't the ID of a friend's unit... Stupid, stupid, stupid me !
