Can’t edit pages (FIXED?), and the smart, add, and delete frame doesn't work :( (FIXED AS WELL?)

My comic is in a draft right now and I clicked edit on a page to hopefully create new frames. But uhh, I just wanted to refresh everything and clicked Control and f5 while in the editing program (add frames, smart frames, etc) Then suddenly it all blanked out and I can’t see or edit my pages.

Edit: I can edit pages now but why doesn't the smart, add, or delete frame work? All I see is just my cursor and the mini blue loading whatyoucallit next to the cursor. it worked on a previous page but it's failing me on the other pages.

Edit #2: The add, smart, and delete frame came back. it's just it can take a while to load it sometimes.
