Thanks for your question. Allow me to answer it for you. As a silver member, you're allowed to send up to 50 inquiries in a week. If you're unable to send more than 50 inquiries in a week, it is most likely because the weekly limit has been exceeded.
Alternatively, you can choose to upgrade to Gold Membership which allows you to send up to 3000 inquiries in a month.
Hope this answers your question.
Thanks and regards,
