Please try the following to see if it is a connection error caused by your firewall / windows settings:

- Download the windows client binary (which is also the command line wallet), unzip to a folder.
- Run 'cmd' from the start menu.
- CD into the folder where you unzipped the client binary.
- Run the client: ballzcoin console
- Within 15 seconds of booting up, the client should start downloading the blockchain. If nothing happens, type 'admin.peers'. If there are no peers, then it is likely you will need to open UDP port 31805 on your firewall.
