Online class need access tomorrow

I have successfully registered for an online course at Berkeley City College and cannot log in to the microsoft area to get to any of the class informaton because i cannot log in. It seems to be a microsoft run program. I have two different emails for peralta college system and neither is letting me sign in. I am getting error messages. I have sent a support help message to [email protected] but no one has responded and class is tomorrow. I have already missed the first two classes. thank you for helping.
