I have been trying to export since last night- rebooted several times and followed the correct instructions to export. Instead it sits at just "Exporting Items" at a standstill. I click on the Collection> Export Library> Files> Zotero RDF and this is the message I recieve- any additional suggestions? Trying to get my file to my professor for my final research paper.

Thank you for any assistance!
