Pretend your password is "hunter2"

Press MR for macro record. Press a G button you aren't using, such as G18.

Then type "hunter2", and press enter.

Press MR (macro record end).

Now, put the cursor in the password field, and press G18 (or whatever you used).

When it gives you the error 37, press G18 again (this will echo your password, which you don't care about, and press enter, which will clear the error box).

Repeat endlessly. Or until you get in, and then crash to desktop.
