I do not synchronize the wallet help please
Wallet update coming in a week, transactions supposedly work in the meantime if synced to 0 hours:

If you still can't sync to 0 after downloading the new wallet, clear the entire %appdata% folder except for the wallet.dat and reinstall wallet AND blockchain with link at the beginning of that thread. Mine wouldn't sync either when I just tried to install the new wallet/blockchain over it.
Issues with "out of sync" and "can't sync to 0" messages are fixed in new AstroCoin Core I posted above. Try it.
But we still awaiting confirmation from dev about new 0.9.1 version.
As for me - I already using new 0.9.1 Core wallet - works nice
