Help needed with photo-paint x5. All of a sudden, my tool options have disappeared.

Help needed with photo-paint x5. All of a sudden, my tool options have disappeared. Example: if I choose the "blend" tool, I now have no options where as before I could select from blend a little, blend alot, soft blend, etc.... Now there is nothing populated in the option window but "custom blend. Any help would be immense. Thank you.
