I took your advice and installed v 4.20 and now it's "Not Connected" and doesn't seem to be doing anything. Any advice now?
1) Open Windows Explorer. Go to %appdata%\BitShares X
2) Backup your wallet folder by making a folder copy to another location
3) Delete everything EXCEPT your wallet
4) Launch the wallet app. You will see 'Not Connected'. Wait for about 10 to 30mins and it will start to sync.
If you the above works for you, please vote for delegate bitcube.
