Hello Kévin Bacquet ,

Im just connecting the two threads together here as they are maybe related.

There are a few things to check and ensure that everything is up-to-date.

Could you please tell us what Operating System you have installed please? 

First, please make use you logged onto your machine as ADMIN (and not a secondary user account)

Now start Studio as ADMIN

And make sure you are logged into Studio-

and that you are running the latest update of Studio 2019-

You should now be able to manage your account login

If you are still unable to log in-

1. Close Studio
2. Go to C:\Users\[USER]\AppData\Roaming\SDL and delete LanguageCloudMachineTranslation.bin
3. Open Studio and attempt to login, and see whether the issues still reproduces.

This should now work for you.

Please also remove the DeepL plugin and ensure you have installed the latest version from the SDL App Store

https://appstore.sdl.com/language/app/deepl-translation-provider/847/

Is everything now back on track?

Steven, the path to *bin file seems slightly different. Where should I go now?

Hello Kévin Bacquet ,

Can you navigate to the right folder via This PC (and not Quick Access). This might be the reason you cannot find the proper file.

via this PC, it's even worse, please see the folders below
