Sorry, but this doesn't make any sense. Please give actual details including versions of all components involved, what exactly you are doing to see a problem, compared to what you expect to see.
I have just set a brand new site with your latest component and the latest CB component.
When I installed dtRegister I got an error as it could not install dir images/dtregister/locations and it said to do it manually. As it dod not say where to do it, I just created it in a number of places.
Then when I go to CB - Tools - Check CB plugins database I get:-
All CB plugin "Default language (English)" Database is up to date.

Dunno if this will help, but I had problems tonight with it and fixed mine so passing it along just in case.
I had an older version installed that wouldn't let me enable it. I had a "lock" icon where the checkbox should have been in the CB plug-in listing page. I clicked on the DT Register Records link and in there I enabled the plug-in (wasn't able to do it from that listing page). Once I did that and saved, the resulting listing page showed the plug-in as enabled and the lock icon wasn't there anymore. From there I checked it, and deleted it. At that point I was able to install the newer version automatically.
