Hello. I have sync problem. Wallet 0.8.6.3. Already removed all from execoin folder (except wallet.dat) but still no sync. Have 5 network connection in wallet. Also, there is a label in wallet (under menu buttons): "Warning: Displayed transactions may not be correct! You may need to upgrade or other nodes may need to upgrade".
Please try
in your config. I started my old linux node, it synced without (ok, almost without
problems.
If you can spare some hashpower, you could mine a bit at

Unfortunately I don't have a miner capable of nfactor 12 or what it is now.
