CH_CTID_TRADER_ACCOUNT_NOT_FOUND

Hello,

   I get this error message:

 {"ProtoMessage":{"_clientMsgId":"t","_payload":[bunch of numbers removed,105,100,61,54,51],"_payloadType":50,"extensionObject":null},"Payload":{"_description":"Unable to find cTID trader account with id=63","_errorCode":"CH_CTID_TRADER_ACCOUNT_NOT_FOUND","_payloadType":50,"extensionObject":null}}

  I am not sure what to put in the id field. I tried my account number and the App ID and neither works.

Thanks
