There's your problem. For some reason it can't create a file on the internal SD card. Not sure why a) your internal card is marked as a readonly system b) why the application manager is trying to write to the internal SD card. Do you have a card in the internal SD slot? Is it formatted VFAT? There is probably a config file that tells the application manager to use the internal SD slot, which can be changed. But for now, I would suggest putting a SD card into the internal SD slot. Craig...
