update from maxi menu pro 9.0.0 to 9.0.2

When I update in the backend of Joomla from maxi menu 9.0.0 to 9.0.2 I get an error message. It's in dutch (my native language) but it says: error when updating COM_INSTALLER_TYPE_TYPE.
I downloaded version 9.0.2 and installed it on top of version 9.0.0 and that went well.
What goes wrong here?

Hi
to update automatically from the joomla updater, you must use the licence key
www.joomlack.fr/en/documentation/miscellaneous/202-license-code

else it works by doing it manually, as you did
CEd

Thanks for your reply. I didn't realize that I had to use this key. I will look at it later today and see how the next update goes.
