As others have suggested here, ask your credit card company for a chargeback as soon as possible. Explain to your cc company that nCrowd is now in foreclosure and isn't selling any more goods or services. Therefore, any unused store credit or vouchers are now useless. I wouldn't bother to wait for nCrowd to resume selling deals again. You could also send your cc company the information about the foreclosure (see the link below) to support your claim. Also, your cc company will likely request proof (e.g., emails with the merchants or the names of the merchants you have spoken to on the phone) that the merchants were unwilling to honor the vouchers. I was able to get a chargeback by doing the above. Perhaps you could ask PayPal for assistance if you used it to purchase the nCrowd deal.
