Custom Robo Arena Online

Sup, I downloaded custom robo arena, and i'm having trouble on WiFi. Whenever i try to enter a friend code it tells me its invalid, and i cant seem to get random matchs online, even when a friend tells me there are alot of them.Anyone else having problems or know how to fix it?

Havnt had any problems, Perhaps try updating your firmware?

Well, I'm using a G6 Flash with a Pass card 3. I just upgraded to u disk manager v4.9d and loader V4.9A.I'm not sure where the best site for updates is, but even with these i am still not able to add friend codes.Any help would be appreciated =)
