While everyone's suggestions seem viable, they do not appear to be helping.
Rather than delete the NK2 file and starting over as someone suggested, you
may want to use our NK2 file editor.
You can find it at

Either or, try finding your NK2 file, and renaming it to a bak file. Next,
delete your profile, create a new one, then rename the Nk2 file to that of
the newly created profile name. (When you create a new profile, it will
create new, empty NK2 file. Delete the new one, and rename the old one to
the new profile name.
