Are there any users of the spaced repetition software Mnemosyne that could help me with a technical issue? I just got the software for my Mac, and I've read in multiple places that you can import plain text files as a card deck. But on my version of Mnemosyne, I see no button saying "import files," and in fact no way at all to add more than one flashcard at a time.

My text editor is Word, and while I can save my vocabulary as a .txt file with Unicode encoding, I don't see any way to export it to Mnemosyne from there. Just to test if I understood the download/import concept at all, I tried downloading one of the free flashcard decks on the site, chose Mnemosyne as the application to open it with, and just got an error message. What am I missing here? Do I need to download a plug-in for importing to work?
