Hey Anh,
MetaBox is telling me that my license key needs fixing, but I am not sure what is wrong.
I've taken a screenshot of the nag/error message and also the MB plugins in use (some are slightly out of date but I am not able to use the auto-updater while this license key issue exists)

When I try re-enter my license key (copied from my metabox.io account page) in the input fields and hit 'save' - I get this error message:
Thanks for your help!
