There was only the possibility to unlock the vault.
Now I reinstalled the latest version and afterwards the the possibility to open the additional options was there again.
Now I have some other problems:
First thing what I already told here: When I end the installation process and mark the option to launch Cryptomator the programm starts but there is no automatic password fill and when I copy and paste the password from KeePass 2 it doesn’t accept the password (but that was already before the case). I have to close the application and restart it and the automatic password fill is working again.
My real problem now is that when I want to lock the vault again (after opening it) with the first klick on lock vault nothing happens. With the second klick I get an error message:
There is no file open in an application that could cause it!
This whole story started after the last WIN 10 Update! No problems before!
