I've got 2 issues at the moment - hopefully some of you know the answer

.
a) My wallet isn't synchronizing anymore (and thus not staking)
It just goes to 88% and then it stops, keeps hanging there.
Restarted and tried 'repairwallet'
b) on Bittrex BLOCKS is still disabled. You can buy and sell but you can't transfer it to an address (or put BLOCKS into bittrex for that matter)
a) copy/backup your wallet.dat file to safe place , remove your blocknet folder from app\roaming\ and run the wallet to download the blockchain again
