Although I do not practice law in the State of New York, here are my initial impressions. First, the general rule is that an insurance policy covers the insured for the applicable dates of the policy. Therefore, if a claim arises during those dates, the insured remains covered regardless of whether the policy is later dropped/discontinued/cancelled. While, in rare circumstances, it may be possible for a policy to become void retroactively, this is unlikely. In any event, however, if you have a claim pending you should hire an attorney, if you have not already done so, to answer these and all other questions associated with the claim.
