I'm not sure if you got my previous request for more information - I need to know:
Did you complete the Google robot challenge?
The robot message is occurring as a result of relatively large numbers of searches you are doing.
If it continues to be a problem after completing the challenge, then you need to go through something to mask your IP, e.g. https://hide.me/en/proxy
Ok, have a good day!Pete.
