Hello chretien,
We will explain more about, what is the local mode?
You might be used your old AxCrypt password(which is different from the one that is exists in our account server) to sign in to the AxCrypt app.
If users used an old AxCrypt account password to sign in with the AxCrypt app, then the AxCrypt app will warn the user with local mode warning text.
You can also use the AxCrypt app in local mode. But the currently used sign in password will be used to encrypt the files. We do not suggest the users to use it in local mode, unless any special cases.
So, Please use your latest password to sign in with the AxCrypt app(internet enabled) without any issues.
Or Please try to clear the AxCrypt local contents by using the AxCrypt file menu File | Options | Clear All Settings & Restart or clicking the switch user button in the sign in dialog
If the above doesn’t help, please provide more information about the issue and some screenshots and write a mail to support@axcrypt.net.
