Custom Order Maid 3D2 It's a Night Magic shop

I got an error message after adapting DLC.

If your Custom Order Maid 3D2 version is older than the DLC release time, you may receive an error that indicates error by lack of data at startup.
You can download and use the latest updater from the following page.
If the problem is not solved after trying the above, please send an inquiry to KISS user support.
