I highly suggest deleting all the blockchain data in your %appdata%/Peepcoin folder EXCEPT the wallet file and restarting. It looks like your 2nd wallet forked, possibly due to a connection interruption. Having that high of a reject rate is abnormal and usually means your wallet is catching blocks at far too low a difficulty and getting rejected by the consensus of the network (in other words, you're forked). Let me know if deleting the block data (leaving the wallet.dat!) fixes the problem. High reject rate usually means something is wrong on your end
