Custom Press - Since update, custom fields do not update when saved.

Hi - since wordpress updated, and custompress updated to the latest versions, I have noticed when I edit existing posts the custom fields created with custompress do not save or update with the changes.

When I create a new post, they appear, but also when i press save draft, or publish, or save non of the entered values actually save. I have tried to load the previous version of custompress, and tried deactivating, and reactivating, this makes no difference.

Any suggestions?
