Pokewalker question!

[laminacourt]

Hey guys, I'm totally confused with the routes on the PW. I know you gain new routes whenever you reach a quota of watts. I have nearly 10,000 watts collected but haven't received Hoenn Field (only 5000 watts needed) and on. I obtained Yellow Forest like most people and haven't gotten a new route since.

Anyone have any idea what's going on? I really enjoy the PW and am ticked I only have less than half the routes.

Thanks guys!
