Some problems:

1. Google map uses a protection mechanism to keep a good quality of service. If one makes too much requests, google map will add its IP address to a blacklist, and you may see a message: "Google Error : 403 forbidden" If this happend, Satellite Maps Downloader will show a messge in log window: May be your IP is banned by Google. Then you must wait for some time or change to another IP.
2. For some area, there are not high precision images on google's server, so may be caused a error when you try to download such images. If this happend, you need to set smaller zoom size to download. (For most areas, the max zoom level is 18)
