Software does not extract data

The software might not extract data in case the ip has been blocked by google. Google does block the ip address sometimes if it finds lot of requests from an ip address.  What u can do is reboot the modem, or the data card. by doing this the ip address to which your computer is connected will be different and google does not know that. This way you can resume the data extraction. Worst case senario, you can install softwares on your computer that will keep changing your ip address so that other cannot track that its just a single computer that is sending so many requests .. and you will not get blocked.
