To clarify, when you mention you're stuck, do you mean that the page has frozen at the loading preview? Or are you unsure of the next steps to take?
If the page is stuck at the loading preview, let's try some basic troubleshooting steps. Such as clearing the browser's cache.
Web browsers collect cache to save time when loading repetitive data and images. Over time these files can become outdated and corrupted, causing issues like the one with the page not loading. I'm including the links for all supported browsers that contain the steps to clear the cache below.
