I downloaded the new wallet but the wallet won't update and is stuck on 99.8% for the last 4/5 hours, any ideas?
Delete all the folders in your %appdata%\Roaming\htmlcoin\ or wherever the blockchain and headers and indexes are stored on whatever OS you're using.
Keep the wallet.dat and I had to keep the peers.dat as well. Took about 15 minutes to resync.
