You need ABC 0.16.1 (or later) from
https://download.bitcoinabc.org ) otherwise you will not be able to finish synchronizing properly.
If you're already running latest version, I would recommend you to stop the client, find the folder containing the
peers.dat file on your machine, and remove that file and also
banlist.dat .
The restart the client. As long as you see it is still synching, let it run until it's synced. It shouldn't take that long if you already had a blockchain downloaded. Otherwise, it depends on your internet connection, but can take up to a day or even longer if you're on a slow connection / computer.
You might want to increase the "dbcache" if your computer has enough RAM to allow it. If you provide details of your configuration I might be able to recommend some settings.
P.S. You can upload screenshots to imgur.com and then use the image icon to paste the image.
