Polar Protainer planning tool - no more power?

Anyone using the exercise planning feature on polar protainer 5 software? I recently had a computer crash and after re-installing protrainer on the new computer (and updating to the latest version online) I can't seem to be able to use power to define intervals. I know I used to. In fact I managed to save my old hard drive and can recall old saved planned exercises - they show the power levels I had set previously, but I cannot even edit these as the planning tool no longer has an option to use power limts - only HR limits.

Am I missing something?
