I used the zip one, and downloaded all the blockchain. First time it gets slow around block 50000, but with time it moved forward and synced. I closed it and open again, and it went back to block 49140, with 2501 blocks remaining, it looks stuck right now, can't sync.
Do we need to add any node?
did you delete everything except wallet.dat?
if yes, then
1)go to debug and
2) do "getpeerinfo" you'll
3) find the problem node, then
4) block it in your firewall settings.
