Some news from cryptsy. Seems they are working on bringeing nav online!

Hello shahim,

Thank you for contacting us and for the information.

NavCoin is already in maintenance mode as our technical support team is working on an update for the wallet. The coin is currently offline and we are unable to view deposits, withdrawals and other transactions until it is back online.

May I ask if you have a transaction that you would like us to take a look at when the coins gets back online?

 
Sincerely,

Cryptsy.com
