Help please, pkm team

I've used Pokesav for quite a while and yes I did use them on wifi though they were legal (without using hex values). I stopped using wifi a while back (used platinum) and now that I have returned, it seems that I cannot connect to anyone. I know that it is not my router or connection. I can see them in wifi room but always get "Failed to respond" error.

What I would like to know is, has filtering and security for hacked pokemon increased for wifi so that you cannot connect unless all pokemon are 100% correct including hex codes? Or does anyone have a solution? And once again, it isn't my security or router.

Also sorry if wrong place but couldn't figure out where to post.

Thanks in advance, Feyted
