I have tried many times to upgrade to Obsidian, but to no avail. I do not know if this is a known problem or I am doing something wrong, but I will try. Another person also said they had problems trying to upgrade to Obsidian.

It says "Transaction not completed".

Edit: Now I can't even add it to the cart and it shows that it is $50 instead of the $20 it was showing! (using Chrome fixes this)
