Well good luck......lets hope there's a fix for us soon.....I'm off to bed....!!..
mine wouldn't sync either, until i grabbed the peers.dat file from another laptop that had the wallet. that's in the .lottoshares folder on linux. fresh installs weren't fixing it, but once i put that peers.dat and of course the wallet.dat, everything started working.
that may not help you now, as you need to have a copy from a fresh install. maybe build a VM, install the wallet and grab the peers.dat from there? or paste your wallet.dat into the VM and call it good?
just tossing ideas out there now......
one thing i have noticed about the blockchain re-update process. usually keeping a copy of wallet.dat and wiping everythign else is good enough to get the job done. with the LTS wallet, i've had to keep the wallet.dat and the peers.dat, since the wallet has been unable to re-create the peer.dat file on its own. could be a bug?
