Everytime I try to go on PSS in Y it has an Error Code and says that I have to update the software, but I already did and it doesnt let me ugrade it more. HELP!
By update did you receive version 1.2? If not then this may be the cause of your problem. To do so go to Nintendo Eshop and go to the Pokemon XY section then you should be able to download the correct corresponding software.
