ML workbench error

Why I have this error while the ML workbench version is 1.4 and pytigergraph version is 1.4:

TigerGraphException: ML Workbench version incompatible. Please reactivate database with the activator whose version matches your pyTigerGraph’s. See for details.

It is likely that your DB is not “activated”. Did you run the activator from that website successfully? Thanks!
