Strange, I don't see it either.
Does the block number reported by your wallet match the explorer?
Does the transaction show up on the explorer if you enter your wallet sending public address?
This transaction appears to be on a fork; its not in my wallet.
Please zapwallettxes, rescan and reindex then resend.
EDIT: I confirm that c-cex wallets instance appears to be down....
