Cannot Updated Plugin + cannot add products to Bundle

Hi,

I cannot add products to the bundle, he pop up doesnt not display any products, and seems to be empty (see html) https://md.reallygoodhosting.net/babywear/muslins/muslin-bundle-4/.

I also cannot add or update the activation key. I add the code, verify it in the envato pop up an then it says “success” but refreshes the page and losses the info.

If this cannot be resolved id like a refund then please?
