ML workbench error

Hi,
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 https://act.tigergraphlabs.com for details.

It is likely that your DB is not “activated”. Did you run the activator from that website https://act.tigergraphlabs.com/ successfully? Thanks!
