Oh, I'm very sorry to hear that. Although there are still several things we can improve, the setup shouldn't crash. You can try reinstalling (I can't explain the crash, so it probably won't happen again). But before you do, it would be great if you could extract the logs from /userdata/logs (if you have a linux machine and can mount the sdcard). If you don't have a linux PC, you can also create a full image of the sdcard (e.g with Win32DiskImager). It would help us to fix the problem in future.
