After installing the Core version of the plugin, I receive this error after clicking on the plugin:

"We have detected that one or more tables with the dknc8N9_ak_ prefix are broken. Akeeba Backup for WordPress will not work properly. Please ask your host to repair these tables and then click here to let Akeeba Backup for WordPress update its database tables."

I had went into the tables via phpmyadmin and attempted to do a table repair, but I was given an error:

"The storage engine for the table doesn't support r..."

The plugin is functional, but is there anything I need to worry about?

There's a slim but existing chance that the database is not broken and this is a false positive. If you are on Windows this is the case. Please do note that the real problem is that you are using an uppercase letter in the database prefix (dknc8N9_) which causes all sorts of trouble on Windows due to a MySQL quirk (I won't call it a bug because they have documented it exists and why it can't be fixed).

Please note that the underlying MySQL issue will prevent you from restoring your site using a different database prefix. You should also be getting a warning linking you to the Q106 warning page on our site. Please read that page to get more insight on what's going on.

In order to fix it you would need to take a backup of your site and restore it with the same database prefix on a Linux or macOS server. Then you'd have to back it up from the Linux/macOS server. Then you'd need to remove all database tables from your Windows server. Finally, you'd need to restore the backup you took from the Linux/macOS server with a new, all lowercase, prefix such as dknc8n9_.
