Facebook disabled, unable to get to code generator

Account was disabled due to suspicious activity. I post nothing offensive or to give cause. Sent Facebood ID and they send email to recover using a link to change password. I am able to change password using the link but when I try to log into my account it requires I use the Code Authenticator to generate a code as part of my dual verification. I can't get to it to generate the code to complete login. I still get my email notifications from FB so the account is there but no way to get further. There are some things that I are very sentimental and I cant imagine never seeing them again.
