Hmm.. I'd need some help with this. I downloaded the application overnight and installed the assistant on my PC. I followed the instructions - I plugged in my N900 via Mass Storage mode, selected the maps, voices I wanted to install, chose the first drive to copy the folders to on device. When the sync with my N900 was done I ran the "SetupMobileMaps" file to install the app on N900. It installs and I can see it in my application list. When i click on it, it starts to open, but closes right after so I can't even run the application. I don't have an SD card in my phone - thought 32GB would suffice for the next few months. When I check the File Browser, all my folders are in the root folder. I reinstalled the application on the phone, restarted the device, but still I can't run the application. Any idea what I should to to make this application work?
