The scheduled Arrow network upgrade occurred overnight and is now complete. 

The block reward has been reduced from 70 to 55 ARW per block to get back on schedule and the transactional limit has been increased to 250kb, thereby increasing transactional throughput.

Please make sure your wallet is up to date.

If you are experiencing a stuck wallet:

1. Close wallet (make sure it's closed)
2. Delete peers.dat
3. Delete old addnodes and update the addnode to:
addnode=52.90.76.26
addnode=45.77.143.128
addnode=85.15.179.171
addnode=65.100.172.203
addnode=34.204.183.163

4- Install v.0.1.8.1
5- Run wallet again
