HiJack Zhai 

 I suggest you first make sure you have the latest updates in Trados Studio, the bell form the top right corner is grey, and if that doesn't help then reset.  

To do this just close Trados Studio and then delete these folders:

%appdata%\Trados\Trados Studio\Studio18\

%appdata%\Trados\Trados Studio\18\

You will lose your plugins, and also your settings, but your projects and other resources will remain untouched. Putting the plugins back is trivial via the integrated appstore.

If you can't find these folders then you need to unhide your hidden files/folders:

Then restart Trados Studio and see if that helped.

Kind regards,

This program cannot be uninstalled or reinstalled now.

Hi Jack,

Try to reset Trados to its default state:

You can reset Trados Studio to default settings by renaming the following folders on your machine:

For Trados Studio 2024:

C:\Users\%USERNAME%\AppData\Roaming\Trados - rename the Trados Studio folder

C:\Users\%USERNAME%\AppData\Local\Trados - rename the Trados Studio folder

C:\Users\%USERNAME%\Documents - rename the Studio [version] folder to Studio [version]_old

Please let me know if this works.

Kind regards,
Anca

Unfortunately, it still doesn't work.
