Just go to %appdata%/bitstar and delete peers.dat, that contains all ips your client as seen. resetting should start you from our master seed nodes.
OK, deleted peers.dat and restarted the wallet but same result as before: still stuck at block 458314 and not synching - after about 15 or 20 minutes the wallet stopped connecting to the network.
What can I do next to get the wallet synching?
Thanks.
