Error in logging in with language cloud on 2017 trados

Hi I need help with logging in with language cloud on 2017 trados. I'm a first time trados user. The login problem occurs when I type in my user id on the login window - specifically, when i type in 'o', the longin window closes and the prompt moves to 'Open' New File of the File menu, if I type in 'a', again, the login window closes, and the prompt moves to 'Advanced Save'. How can I fix this problem?
