Help! shutdown after wifi-map-loading

Hi all,
after succesfully loading a map via WiFi (Tokyo, detail=2, 16, loads 340 tiles) my PSP shuts down when selecting this map! The tiny NY-map works fine, but my own doesn´t (well, the format is different. my WiFi-loaded map has these resolution-folders, the standart-NY-map doesn´t. I´m a little confused ..).

I´m on 4.01m33-2 with mapThis 5.20 and without any GPS-reciever. (but will get a psp290 once I´m in Tokyo).
And on OSX, so the WiFi-DL is my only option.

I really need a nice tokyoMap, my flight goes next week ... (and unfortunatly "Maplus" is japanese only!)

any ideas, anyone?

Thanks in advance,

b-viz

Any Ideas for a macuser how to get a working tokyo-map?

Well .. so far I didn´t manage to get a map via WiFi, so I installed xp and GMDL on my mac ... (not funny at all).
And I had to diconnect and reconnect my modem after about 600 tiles due to googles IP-ban ... quite annoying. But at least I got my tokio-map ..
Does anybody know how to avoid this? (I guess its the same IP-ban that keeps me from downloading mapdata via wifi ..)

Thanks in advance,
