an internal error has occurred

3.50-1.50-3.03oe-c---1.50--3.40oe-a----3.52m33----3.52m33-4
after I upgrade psp to 3.40oe-c,3.52m33,3.52mss-4, I got the message "an internal error has occurred", turn to the blue screen in multiple language, click "O" then I was asked to setup name, time zone and date etc. Map this can be start and sats can be fixed in 2 min. The problem is that map this is easy to be crashed, after waking up the psp. I have tried different version PRXs. I really dont know what the problem is.

Do you mean it easily crashes after you return from standby? That is to be expected, AFAIK MapThis doesn't take standby into account, so when you wake the thing up, it loses all the open files and thus crashes when it needs a new tile.

If you go back to the map overview (press Select in map mode), standby, wake up, choose a map again, everything will work fine.

thanks, make sense.
