Free Edition will not open with more than 500 comics. Is there a way to remove comics?

[Chris Stewart]

I am trying to open Comic base.  It has the following message:
The free edition is limited to handling collections of 500 or less comics.  To work with the database you've chosen, you'll need to upgrade to the Express, Professional or Archive Edition.

Is there a way to remove comics so that I am still within the limit.  Can I edit the database directly?

once you pass 500 inputted comics, you'll need to purchase a higher edition (express, pro, or archive) to unlock your database.
