I also got no connections when updating. Here is what I did to fix the issue:
Go to https://chainz.cryptoid.info/xpy/#!network
Click on the node list button for the top entry: /Satoshi:0.6.3/Peercoin:0.4.0/Paycoin:0.3.0.2(v0.3.0.2)/ then copy and paste that list to your paycoin.conf file. Close/Reopen wallet. It should sync. If not then you need to redownload the blockchain from scratch, which I had to do but it eventually worked and is now synced up.
