Mining Structures

I am using the wizard to create a new mining structure and getting the error at the time of selecting the datamining technique like either microsoft decision tree or microsoft timeseries etc.,

"Unable to retrieve a list of supported data mining algorithms. Make sure you are connected to the correct Analysis Services server instance and the Analysis Services server named localhost is running and configured properly. You can continue with a default list of data mining algorithms."

What is that means?

Thanks in advance,
