RTFM Create Custom Field error

I have a new installation of RT and RTFM 3.0.10. I have the following
problem when trying to configure RTFM. To start with, I understand I
need to create some custom fields, but when I try to create one, I
receive the following error:

RTFM Error
RTFM Error
Could not create CustomField

Since I’m not able to create any custom fields, I can’t create a class:
I receive the following error when trying to do so:
RTFM Error
RTFM Error
Internal Error: Couldn’t execute the query 'INSERT INTO FM_Classes
(LastUpdatedBy, SortOrder, Created, Name, Description, Creator,
LastUpdated) VALUES (?, ?, ?, ?, ?, ?, ?)'Table ‘rt3.FM_Classes’ doesn’t
exist

I don’t know if this indicates that the initial installation was not
correct?
I would appreciate some guidance here.
Thanks,
Joe.

Yes, follow RTFM README. You didn’t init your RTFM DB part.
