I was in contact with c-cex support recently. They said the github official wallet source link needs to be updated with the current wallet data in order to compile the data. They seem unable to use the current wallet in zip file. The maryj balances disappeared but all balances are kept archived on the exchange. Adam said he is working on updating the github wallet data, then we can ask c-cex to re-sync to the network. I don't believe our maryj are lost, just invisible for now.
