I just got an answer (in the Adobe forum in French) that deleting also the ThumbDatabase did not succeed either. He deleted two effects.
Michel, thanks for posting back! It looks like he deleted the effect from their "storage" folder. This explains why deleting/rebuilding those two databases didn’t do the job.
I won't get an answer before tomorrow. Seems he wants to install anew on a second computer and try to copy the data of the FR_fr subdirectory in the first computer after taking copies for safety.
I believe it will work; I have done it before.
I am assuming he is talking about Effects (photo effects) and, if he is on Windows, it is just a matter of navigating the path below and copying/pasting the appropriate files. He will need to copy/paste the .atn file as well as the .xml, .png, and .thumbnail.jpg file.
I am with PeteB on this one; a simple System Restore will put you back to before the effect was deleted --- provided you don't play around too long.

On a poverty-level Kentucky budget, a 24-exposure roll of film would have two Christmases and a summer vacation on it and we might have to wait another six months before being able to afford developing the film.
I still have trouble remembering that it doesn't cost anything to take thousands of pictures; it just almost seems impossible to be true.
System Restore is a Microsoft® Windows® tool designed to protect and repair the computer software. System Restore takes a "snapshot" of the some system files and the Windows registry and saves them as Restore Points. When an install failure or data corruption occurs, System Restore can return a system to working condition without you having to reinstall the operating system. It repairs the Windows environment by reverting back to the files and settings that were saved in the restore point.
It does not affect your personal data files on the computer.
I would not trust a Windows restore, but a restore made by my Acronis backup system should work. The trouble is that I don't backup regularly, only at intervals or when there has been some OS or software updates. I may have to reconsider the backup frequency. I have taken care to keep only the OS and software files on my C: drive and to move what I can on other drives: documents (OneDrive and Dropbox...) That way I can keep my C: drive in a 150 GB partition which is backed up in about 45 minutes. I also keep my catalogs elsewhere. Those are saved after each editing session together with my library through Microsoft Synctoy.
Anyway, since that is not my personal issue, I am still waiting for some feedback from the user I was trying to help.
Thanks to all for your contributions and a happy new year to everybody .
