Message taken from Dev-updates on Discord:

@everyone The new windows wallet is now available for download at this link. https://nycoin.info/  
There has not been a significant code change, just a bit of tidying up and a makeover so this should work with the block data you have already downloaded.
That being said, before downloading, BACK UP YOUR WALLET AND BLOCK DATA FILES!!!
We have tested the wallet and have confidence that it works but you should always take precautionary measures to insure that your data is safe.
We will have a mac build put up on the site as soon as we can. Thanks for bearing with us! More fun updates are coming!

With this update comes some much needed maintenance such as removing the old alert system and mining functions.
 We have reduced the amount of items that will cause an Anti-Virus to flag the program from 22 to 2.
You may still need to white-list the wallet with your AV. Be sure you wait for the wallet to sync completely before first use.
