[JavaScript Error: "Could not remove the file at D:\Program Files (x86)\Zotero\Data\storage\L6QY625Z"]
You seem to have your Zotero data directory within an old Program Files folder. That's extremely incorrect, and you should move it out, ideally to the default location.
(That might not even be your current Program Files folder for Zotero — the 64-bit version shouldn't be within "Program Files (x86)". Once you've moved the data directory out, you can likely delete that "Program Files (x86)\Zotero" folder.)
