Block explorer and wallet are working fine for me, which wallet version are you using?
1.0.0.1 from here https://github.com/palmd/GoldPieces/releases
What block explorer are you using? http://cryptobe.com/chain/GoldPieces is stuck at block 1188621
I use cryptobe and currently their block explorer is at 1188800 which is the same as my wallet.
