Taking way too long

It's been six hours and my PDF is not even converted to Anki flashcards. I paid to upgrade to the premium plan so I can save time when creating a deck. But it would have been much simpler for me to manually create these cards myself, so I don't have to wait around and waste time for it to finish (never knowing if it actually will, since the loading screen has been the same for six hours). I don't even know if my cards will be generated by the time my test comes since it's taking forever.
