Sorry for causing you this trouble!
After you hitting the "search" button,the program will search free random proxies on the first page. If there are no proxies available on the first page, the program will not move to search proxies on the next page but stop.
TO solve this problem, you can click button" Assign a proxy for each account".This button can search proxies for you from the first page to the last page. If there are no proxies available on one page, it will move to search from the next page. You can have a try and to see the result.
Thanks for your support and understanding!
Sincerely,
Helen in Lively Marketing Tools 24*7 Hours Support Team
