edited course.conf, cannot proceed at attempted log in

At the urging of our local administrator, I edited course.conf so as to change send_mail permission for user role ta. But I think I may have erroneously used

%permissionLevels(send_mail => "ta");

instead of what I take to be the proper syntax

%permissionLevels = (send_mail => "ta");

Now when I log in I get the error message, shown below, saying my Username or Password is invalid. But I'm quite sure I have those correct (they are the same as work for another course, on the same server, where nothing is amiss).

Although there's a Continue button within the error page, clicking it just takes me back to the same error page.

Is this something that only the administrator can fix? How?

The error message s as follows:

Warning -- there may be something wrong with this question. Please inform your instructor including the warning messages below.

Invalid user ID or password.

The problem with what you've added is that it did exactly what you feared.
You have replaced the complete list of permissions for the course with a hash containing just a single permission.
What you want is something like the following instead:
$permissionLevels{send_mail} = 'ta';
IIRC, the 'send_mail' permission refers to being able to send email from within a pg problem (for essay questions, etc.). Are you trying to change who can use the "email professor" button? If so, you should be changing the 'submit_feedback' permission instead (which can be done from the Course Configuration link on the web interface).
