my windows wallet says "No block source avaliable..."
What could be the problem?

Open Windows default file explorer, type %APPDATA% on address bar. Open the "PKR coin" file and create/edit pkrcoin.conf with the following data:
rpcuser=myuser
rpcpassword=mypass
addnode=37.187.70.70
addnode=79.108.180.52
addnode=178.32.34.119
addnode=198.50.145.238
addnode=37.187.39.206
rpcport=8776
