This mean that ActiveTransfer server is not initialized correctly. The log files in the directory profiles/IS_default/logs should have some information on what is going wrong.
May be you do not have license file for ActiveTransfer at the location \packages\WmMFT\config?
BTW, since you are using 10.11 version, ActiveTransfer has its own UI, running at the port 9100. Some of the new features added in the product may not be available in MWS UI.
