Give it a bit of time.
Due to the fact that there are only a relatively few people staking at the moment (probably because a lot of people are keeping their coins on exchanges instead of their own wallets), network blocks are being generated less frequently than they otherwise might be. This is the nature of all PoS coins. People need to stake in order to increase network activity.
Your wallet will sync, just give it some more time. In the meantime you can still perform transactions which will be valid (they may simply take a bit longer to confirm, is all.)
