Hello avglobalconcepts,
Please note that we implemented search limits because currently it's been impacting other customers from running searches, because some customers are doing a lot more searches than ideal. To help ensure that all our members get a fair share of searches our developers have added a 30 searches for every 7 days limit. Should you get prompted by the Market Search Labs, then you will have to wait for your limit to reset before doing another set of searches.
Please let us know if we can help you with anything else.
