I can't use it either and all of my projects are also missing. Very frustrating. 3 month after my return period ends this happens. Pretty awful.

Same with me! Preety Awful!

It's the same for me. I have already stopped programming because I believe the project is a scam. I couldn't even finish a single page.
I ask the Appsumo team to step in and take action. I purchased the highest tier level – for what? If the problem is not resolved, I request a refund.

well this is what they always do to customers... seems like a cash grab
