Don’t do free upgrade – MindNode - Mind Map & Outline Review

I upgraded using the free option for Mindnode 4 purchasers. It allowed me to update, and I expected to be able to use the app. Now all of my documents are locked and I cannot edit them without paying to upgrade. And I can’t downgrade to mindnode 4. This is unacceptable. You tricked me into upgrading by making me think I qualified fo a free upgrade sine I had purchased 4 previously, but really all that happened is my paid app was replaced by the free version that makes me do a free trial or purchase. Completely unacceptable.
